BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a wheel measuring system, a wheel measuring method and a wheel-related product sales method. More specifically, it relates to a wheel measuring system and a wheel measuring method for measuring and maintaining a wheel and the periphery thereof at a garage, a vehicle parts shop etc. and to a wheel-related product sales method using the measuring system and the measuring method. [0003] 2. Description of Related Art [0004] A wheel including a rim, a hub and a tire and the periphery thereof including a brake and a suspension are important for a vehicle. [0005] As mileage of a vehicle increases, pressure change and surface wear of a tire of a wheel are caused, and a brake pad wear of the periphery thereof are inevitable. Status values such as the tire pressure, the tire wear and the pad wear are important as maintenance data of a wheel and the periphery thereof. It is usual that these values are measured on business at institutions such as a vehicle dealer, a maintenance service factory, a garage and a tire shop. It is important for these institutions to maintain the wheel and the periphery thereof as a chance to suggest the end user when the tire needs to be replaced or as a service improvement for the end user. These institutions make a list of the measurement values etc. to consult replacement of the tire or so. [0006] The tire pressure is measured by connecting a pressure gauge with a valve of a tire. State of the tire wear is determined by measuring tread depth by a depth gauge. State of the pad wear is determined by measuring thickness of the brake pad by a calliper. Maintenance data of the other components is measured by existing measuring instruments in accordance with various situations [0007] However, conventional measurement operation of the wheel and the periphery thereof has the following problems. [0008] (1) Generally, the measurement operation of the wheel and the periphery thereof are carried out at each wheel. On the other hand, a report for the user should include all wheel data. Accordingly, it is necessary to repeat measuring each wheel and the periphery thereof and transcribing the measurement values into a record sheet for a plurality of wheels attached to one vehicle and the peripheries thereof, so that it takes a lot of time. [0009] (2) Since the transcribed paper sheet is hard to maintain because of difficulty of search and space required to keep the sheet, the measurement data is manually input into a computer. When the end user requests a maintenance report after the manual data input, it is necessary to re-process the data for the report. Accordingly, it takes furthermore time. [0010] (3) Since the transcription and the manual input are necessary as described above, possibility of human error on the manual transcription cannot be eliminated. [0011] With the above measurement operation, sales activity of a wheel-related product having a wheel including a rim, a hub and a tire, the periphery thereof including a brake pad and brake fluid, and operation including adjusting air pressure, cleaning and adjusting the brake are carried out. [0012] For example, as to tire replacement, an operator judges that tread depth of a tire becomes out of tolerance and selects a suitable tire for the vehicle from a catalogue etc. to suggest replacement to an owner of a vehicle. As to brake pad replacement, after pad wear is measured, the operator similarly suggests replacement to the owner. As to the other components, after measurement by predetermined measuring instruments, the operator similarly suggests replacement to the owner. [0013] However, conventional wheel-related product sales method has the following problems. [0014] (1) Measurement operation for maintenance data on a wheel and the periphery thereof, forecast of maintenance operation timing for the wheel and the periphery thereof on the basis of data obtained by the measurement operation, and selection of recommended maintenance operation for the vehicle based on the forecast are independently carried out. Accordingly, whole operation is inefficient. [0015] (2) Expert knowledge is required to forecast the maintenance operation timing and select the recommended maintenance operation. Accordingly, it takes a lot of time for training an operator. [0016] (3) Possibility of losing business opportunity by wrong forecasting the maintenance operation timing or selecting the maintenance operation cannot be denied. SUMMARY OF THE INVENTION [0017] An object of the present invention is to provide a wheel and the periphery thereof measuring system and a measuring method for easily inputting, utilizing and managing maintenance data on a wheel and the periphery thereof such as measurement data of a wheel and the periphery thereof and customer data.

In this case, the tread depth of the tire may preferably be measured on at least three points of inside, middle and outside in width direction of a tread surface of the tire. [0023] According to the above arrangement, data to inspect tire surface condition is more precise than an arrangement in which measurement data of tread depth is measured on only one point. Accordingly, the tire surface condition can be inspected more precisely. [0024] In the present invention, the data displaying portion may preferably display a graph coloured corresponding to a selected measurement value. [0025] According to the above arrangement, length and colour of the graph can be changed corresponding to the value of tread depth or brake wear.

[0033] According to the above arrangement, even when the data processor receives measurement data from a plurality of wheel gauges, the data processor can identify which wheel gauge has transmitted the measurement data. Accordingly, interference among the plurality of the wheel gauges can be prevented, so that operation efficiency can be improved. [0034] In the present invention, the received measurement data may preferably be registered in a database including a plurality of measurement records. [0035] According to the above arrangement, the received measurement data can be utilized for maintenance of the wheels and the peripheries thereof in various ways.

Accordingly, operation efficiency can be improved. [0050] In the present invention, the wheel measuring method may further include the step of displaying the transmitted measurement data in graphic representing positions of wheels or wheels and a spare tire in a vehicle.

Incidentally, when the cancel button B1602 is clicked, the process is terminated at the stage and the screen P11 is displayed. [0256] Incidentally, since any existing computer software technique can be used for the aforesaid functions and the aforesaid data input screens, detail description will be omitted. [0257] In the aforesaid first embodiment, the measurement data can be obtained and edited, for instance, as follows. [0258] In FIG. 24, an operator operates the computer 32 to check presence of a measurement record 301 of a target vehicle (the measurement record 301 of the corresponding target vehicle is loaded based on the vehicle code 3031) (Step S101). [0259] When there is no corresponding measurement record 301 of the target vehicle in the database D, the operator creates a new measurement record 301 by the computer 32 (Step S102). [0260] The operator checks whether there is a change in the loaded measurement record 301 or whether there is an input error in the new measurement record 301 (Step S103). [0261] When there is any change or any input error, the operator operates the computer 32 to revise the data by the vehicle/customer data group editing function 395 and/or the tire data group editing function 396 (Step S104). [0262] When the operator operates the computer 32 to execute the measurement data input function 392 after the above steps (Step S105), the operator uses the pressure gauge 11 and the depth gauge 12 to measure the tires 21 and 22 (Step S106). When the measurement data is obtained, the operator transmits the measurement data to the data processor 13 (Step S107). [0263] After transmitting one measurement data, the operator checks whether the data processor 13 has received the measurement data (Step S108). [0264] If the measurement data has not been received, the operator transmits the measurement data again (return to Step S107). [0265] If the measurement data has been received, the operator checks whether the measurement data displayed on the computer 32 is acceptable (Step S109). [0266] If the measurement data is abnormal, the operator confirms measurement validity by re-measuring etc. (Step S110). [0267] If the measurement data is acceptable, the operator continues the measurement, i.e. repeats Step S106 to S110 to obtain the measurement data of predetermined number of pressure value and tread depth (inside, middle, outside) (Step S111). [0268] The measurement data can be input and edited, for instance, as the above steps. [0269] Incidentally, the operator can save the input and edited measurement record 301 in the database D whenever the whole measurement record displaying screen P11 is displayed on the computer 32. [0270] After inputting and editing the measurement data, the operator can execute the print function 398 by connecting the computer 32 to the printer 4. Further, the operator can execute the data export function 399 to export the measurement record 301. [0271] Incidentally, the aforesaid steps are examples and it is not necessary to always take the above steps. For example, the tire data groups 305 to 309 can be input before the customer data group 304 is input in the data processor 13. [0272] According to the present embodiment, following effects can be obtained. [0273] (Effect 1) The data processor 3 can process and display the measurement data received from the pressure gauge 11 and the depth gauge 12 on predetermined format without manual transcription by the operator. Accordingly, the need of the conventional manual transcription into the computer can be eliminated. [0274] (Effect 2) The data processor 3 can be in wireless communication with the pressure gauge 11 and the depth gauge 12. Accordingly, no cable will obstruct the operation in measuring. Further, measuring position and location of the data processor 3 are not restricted by cable length limitation. [0275] (Effect 3) The tread depth is measured on three points of inside, middle and outside in width direction of tread surface of tire, so that more precise data to inspect tire condition can be obtained than only one point. Accordingly, the tire condition can be inspected more precisely. [0276] (Effect 4) The data processor 3 displays the measurement data as the colour graph corresponding to the measurement value by the data processor 3, so that length and colour of the graph can be changed corresponding to the tread depth value. Accordingly, the tread depth can be easily determined. [0277] (Effect 5) Data of five tires of one vehicle can be processed together. Accordingly, the tires can be easily compared with each other, so that operation efficiency can be improved. [0278] (Effect 6) Each measurement data is separately transmitted from the tire gauge each time the measurement data is obtained by the tire gauge, and the input order of the measurement data into the data processor 3 is set to an order for the operator to move around the vehicle. Accordingly, it is not necessary for the operator to input the position of the tire each time the tire is measured, so that the operation efficiency can be improved. [0279] (Effect 7) The received measurement data is displayed in a graphic representing the tire position of the vehicle, so that each measurement data can be displayed in association with actual tire positions. Accordingly, the display position of the measurement data can be easily identified. Further, the measurement data of each tire can be easily compared, so that the operation efficiency can be improved. [0280] (Effect 8) The received measurement data is identified based on the transmission ID set to each tire gauge, so that the data processor 3 can determine which tire gauge has transmitted the received data even when receiving the measurement data from a plurality of the tire gauges. Accordingly, interference doesn't occur even when a plurality of the tire gauges are simultaneously used, so that the operation efficiency can be improved. [0281] (Effect 9) The received measurement data is saved in the database including a plurality of measurement data. Accordingly, the received measurement data can be variously utilized for tire maintenance. [0282] (Effect 10) The measurement record is identified with the vehicle registration number and the measurement data/time, so that the vehicle registration number as principal vehicle identification can be used for identifying the data. Accordingly, the database can be easily managed. [0283] (Effect 11) The database includes the measurement data group, the customer data group, the vehicle data group and the tire data group. Accordingly, an ample data can be utilized, so that flexible services can be provided to the customers. [0284] (Effect 12) The measurement data can be printed out with the status information, the comment for customer etc. Accordingly, useful materials for customer service can be made. [0285] (Effect 13) The created data of the measurement record can be exported. Accordingly, the created data of the measurement record can be used in the other software, so that the application range of the measurement record can be extended. [0286] [Second Embodiment]
[0287] As shown in FIG. 25, a wheel measuring system 50 of the present embodiment has a pressure gauge 11 for measuring air pressure of tires 24 and 25 of trucks 23, a depth gauge 12 for measuring tread depth of the tires 24 and 25, a data logger 56 for receiving data measured by the pressure gauge 11 and the depth gauge 12 and temporally saving the data, and a data storage terminal 57 for receiving, storing and processing the temporally saved data. [0288] The trucks 23 as the measurement object have sixteen tires 24 and two spare tires 25. Each set of four tires 24 is attached to one axle. [0289] Since the pressure gauge 11 and the depth gauge 12 are the same as in the first embodiment, specific description will be omitted. [0290] The data logger 56 including a transceiver receives and temporally saves the measurement data transmitted from the pressure gauge 11 and the depth gauge 12 to transmit the measurement data of one vehicle to the data storage terminal 57 together. [0291] The data storage terminal 57 combines separately input vehicles/customers data with each received data to set a database and displays each measurement data on a display 726. Further, the data storage terminal 57 processes and outputs each data to a colour printer 4. The data storage terminal 57 basically has all functions included in the data processor 13 of the first embodiment. [0292] The data logger 56 will be specifically described first and the data storage terminal 57 will be described second. [0293]FIG. 26 shows a block diagram of hardware of the data logger 56 of the present embodiment. [0294] The data logger 56 of the present embodiment consists of a PDA (personal digital assistant) 62, into which a PC card (PCMCIA standard card) 61 for receiving the data from the pressure gauge 11 and the depth gauge 12 is inserted. [0295] The PDA 62 temporally saves and transmits the received data to the data storage terminal 57, and has a touch panel 621 to input commands, various data etc., a command input pen 622, operation buttons 623, a SDRAM (Synchronous Dynamic Random Access Memory) 624 as a memory, a CPU 625, and the display 626. [0296] Incidentally, the PDA 62 is commercially available and has a wireless communication function with a commercially available computer. [0297] The measurement data is transmitted, received and saved by a data processing program DP1 run by the CPU 625 of the PDA 62. [0298] A data saving structure DS of the data logger 56 of the present embodiment has measurement records 301A as in the database D of the first embodiment. However, all data can be saved in the measurement records 301A in order to get rid of the reference tables. Data of each measurement record 301A is transmitted to the data storage terminal 57 to store the data therein. [0299]FIG. 27 and FIG. 28 show a specific arrangement of the measurement record 301A of the present embodiment.

[0301] The tire model data 3051A has a manufacturer 3501A, a model 3502A, a width 3503A, a size 3504A, a rate 3505A, a speed 3506A and a type 3507A. [0302] The measurement data group 3052A has a tire air pressure 3053A and a tread depth 3054D including an inside tread depth 3054E, a middle tread depth 3054F and an outside tread depth 3054G. [0303] The tire identification data 3056A has a maintenance detail 3602A and a maintenance date 3603A. [0304] Since each element is the same as in the first embodiment, specific description will be omitted. [0305] While the above data saving structure DS is used, the following various data process is performed in the PDA 62 of the present embodiment. [0306] As shown in FIG. 29, a data processing part 69 is loaded on the PDA 62 of the present embodiment by software. [0307] The data processing part 69 has a screen displaying function 690, a new measurement record creating function 691, a measurement record editing function 692 and a measurement record searching function 693.

The cancel button B2402 is used to terminate the process at the stage. [0332] The aforesaid screens P21 to P24 are used to perform following functions 691 to 693 in the data logger 56. [0333] (1) New Measurement Record Creating Function 691 [0334] This function is used to create a new measurement record 301A in the SDRAM 624. [0335] The function 691 is performed based on the following process. [0336] When the new record creating button B2102 in the measurement record list displaying screen P21 is clicked, the tire position block diagram displaying screen P22 is displayed. [0337] When a vehicle code 3031A, a customer code 3041A, a pit name 3023A, and an operator code 3022A are input in the vehicle code input field F2202, the customer code input field F2204, the pit name input field F2206 and the operator code input field F2208 respectively on the screen P22, the input data is displayed in the respective input fields F2202, F2204, F2206 and F2208. [0338] When one of the tire position blocks F2222 is selected while at least vehicle code 3031A is input in the field F2202, the tire data group input screen P23 of selected tire position block F2222 is displayed. [0339] Incidentally, when the save button B2201 is clicked on the screen P22, the input data temporally saved in the SDRAM 624 is saved as a measurement record 301A. When the clear button B2202 is clicked, the input data in each input field of the screen P22 is cleared. When the cancel button B2203 is clicked, the process is terminated at the stage and the screen P21 is displayed. [0340] When measurement data, tire model data and tire identification data are input in the measurement data input fields F2303, the tire model data input fields F2305 and the tire identification data input fields F2307 respectively on the tire data group input screen P23, the input data is displayed in the fields F2303, F2305 and F2307. When the measurement data with predetermined transmission ID is received, the data is automatically input into the fields F2303. [0341] When the OK button B2301 is clicked, the input data is temporally saved in the SDRAM 624 and the screen P22 is displayed. When the clear button B2302 is clicked, the input data on the screen P23 is cleared. When the cancel button B2303 is clicked, the process is terminated at the stage and the screen P22 is displayed. [0342] When the OK button B2301 is clicked to display the screen P22, colour of the code and the background thereof of the tire position block F2222, in which the measurement data etc. has been input, is inverted, and the tire position block F2222 of the next target tire is blinked. The next target tire is paired with the measured tire, and when the data input of the pair of the tires is completed, next pair of the tires adjacent to the pair of the measured tires in the counter clockwise direction is measured. Order to measure an inner tire and an outer tire is selectable. For example, when the code A1 is selected first in FIG. 31, the subsequent measurement order is A2, B1, B2, C1, C2 . . . [0343] When data of all the tires has been input by the aforesaid method, colour of the code and the background thereof of all the tire position blocks F2222 is inverted. [0344] (2) Measurement Record Editing Function 692 [0345] This function is used to edit a measurement record 301A saved in the SDRAM 624. [0346] The function 692 is performed based on the following process. [0347] When a measurement record 301A in the measurement record list displaying field F211 is selected to edit on the measurement record list displaying screen P21, colour of characters and the background thereof of the vehicle code displaying field F2111, the customer code displaying field F2112 and the measurement date/time displaying field F2113 of the corresponding measurement record 301A is inverted. When the edit button B2102 is clicked in this status, the tire position block diagram displaying screen P22 reflecting the selected measurement record 301A is displayed. Since similar process to the new measurement record creating function 691 is carried out after the above steps except the selected measurement record 301A is reflected, specific description will be omitted. [0348] (3) Measurement Record Searching Function 693 [0349] This function is used for searching a measurement record 301A saved in the SDRAM 624. [0350] The function 693 is performed based on the following process. [0351] When the search button B2103 is clicked on the measurement record list displaying screen P21, the measurement record searching screen P24 is displayed. [0352] When a search word is input in the search word input field F2402 on the screen P24, the measurement record 301A including the input search word is searched and displayed on the screen P21. Incidentally, when the cancel button B2402 is clicked, the process is terminated at the stage and the screen P21 is displayed. [0353] Incidentally, since any existing computer software technique can be used for the aforesaid functions and the aforesaid screens, specific description will be omitted. [0354] Since the measurement record 301A is transmitted from the data logger 56 to the data storage terminal 57 by a function included in any existing PDA 62, specific description will be omitted. [0355] Next, the data storage terminal 57 of the present embodiment will be described. [0356] The data storage terminal 57 consists of a notebook computer 72, into which a PC card 71 for receiving data from the data logger 56 is inserted. [0357] The computer 72 saves and processes each received measurement data from the data logger 56, and has the same hardware arrangement as the computer 32 of the first embodiment. Specifically, the computer 72 has a keyboard 721, a mouse 722, a hard disk 723, a CPU 724, a memory 725 and the display 726. Specific description and drawings will be omitted. [0358] Incidentally, the computer 72 is commercially available and configured to communicate with an external device by setting predetermined configuration. [0359] A data processing program DP2 run by the CPU 724 performs various data processing in the computer 72. [0360] Since structure of a database D2 of the present embodiment is basically the same as in the first embodiment, figures and specific description will be omitted. [0361] Incidentally, the second embodiment is different from the first embodiment with respect to having more registration fields for tire data group in a data table following to increase in the number of tires. [0362] While the above database D2 is used, the following various data processing is performed in the present embodiment. [0363] As shown in FIG. 33, a data processing part 79 is loaded on the computer 72 of the present embodiment by software. [0364] The data processing part 79 has a screen displaying function 790, a new measurement record creating function 791, a measurement data input function 792, a displayed measurement record saving function 793, a saved data loading function 794, a vehicle/customer data group editing function 795, a tire data group editing function 796, a measurement data editing function 797, a print function 798, an export function 799 and a received data displaying function 79A. [0365] Since the functions 790 to 799 are the same as the functions 390 to 399 of the data processing part 39 of the first embodiment, specific description will be basically omitted. However, since the screen displaying function 790 is partly different from the screen displaying function 390, description for the function 790 will be supplemented. Further, since the received data displaying function 79A is unique to the data processing part 79, the function 79A will be specifically described below. [0366] The function 790 basically displays the same screens as in the function 390 of the first embodiment. Specifically, the function 790 displays a measurement record displaying screen P31, a vehicle/customer data group input screen P32, a tire data group input screen P33, a measurement data input screen P34, a print preview displaying screen P35 and an export executing screen P36. [0367] Though the aforesaid screens P31 to P3A are basically the same as the screens P11 to P1A of the first embodiment, there is difference based on difference in the number of tires. Accordingly, the measurement record displaying screen P31 and the print preview displaying screen P39 both being remarkably influenced with the difference will be specifically described below, and specific description of the other screens will be omitted. [0368]FIG. 34 shows the measurement record displaying screen P31 of the data storage terminal 57 of the present embodiment. [0369] The screen P31 is displayed on the display 726 when the data processing program DP2 is started, and includes a vehicle code displaying field F311, a vehicle/customer data group displaying field F312, a vehicle image displaying field F313, measurement data displaying fields F314, an axle configuration selecting field F315, a command buttons displaying field F316, and a tread depth tolerance value displaying field F317. [0370] Fields having the same functions as in the measurement record displaying screen P11 of the first embodiment will not be specifically described. [0371] Though the vehicle/customer data group displaying field F312 has similar arrangement to the vehicle/customer data group displaying field F112 of the first embodiment, the field F312 doesn't have the vehicle/customer data group editing button B1121 as shown in FIG. 35. [0372] The field F313 is displayed in the centre of the screen and used to display a vehicle image F3131, left and right side tire images F3132, spare tire images F3133 and codes F3134 representing position of each tire as shown in FIG. 36. [0373] The fields F314 are displayed at eighteen positions, which are on the middle right, on the middle left and in the lower middle of the screen in accordance with the positions of each tire image F3132 and F3133 of the vehicle image displaying field F313. As shown in FIG. 37, each field F314 has a code displaying field F3141 representing position of a tire, a pressure value displaying field F3142 of each tire and a tread depth (minimum value among inside, middle, outside values) displaying field F3143. [0374] Each field F3142 and F3143 has a function as a button for commanding to display the measurement data input screen P34. When each field F3142 or F3143 is clicked twice by the mouse 722, the measurement data input screen P34 of the selected field is displayed. [0375] The axle configuration selecting field F315 is displayed on upper right of the screen and includes an axle configuration displaying field F3151 and an axle configuration input field F3152 as shown in FIG. 38. Incidentally, the field F3152 can be input by drop menu. [0376] When an axle configuration of the field F3152 is changed, the vehicle image displaying field F313 and the measurement data displaying fields F314 are changed in response to changing the axle configuration. [0377] The print preview displaying screen P35 (not shown) of the data storage terminal 57 of the present embodiment is different from the print preview displaying screen P15 as in the difference between the measurement record displaying screen P11 of the data processor 13 of the first embodiment and the measurement record displaying screen P31 of the data storage terminal 57 of the second embodiment. [0378] Next, the received data displaying function 79A will be described. [0379] (1) Received Data Displaying Function 79A [0380] This function is used to display received data from the data logger 56 on the measurement record displaying screen P31. [0381] The function 79A is performed based on the following process. [0382] When a measurement record 301A is received from the data logger 56 while the measurement record displaying screen P31 of the data storage terminal 57 is displayed, the received measurement record 301A is displayed on the screen P31 and the database D2 is searched based on the vehicle code 3031A of the received measurement record 301A. If there is the corresponding measurement record 301B in the database D2, the vehicle data group, the tire data group and the customer data group thereof are displayed, which are not included in the measurement record 301A. [0383] Incidentally, since any existing computer software technique can be used for the aforesaid functions 790 to 79A and the aforesaid screens P31 to P3A, specific description will be omitted. [0384] In the second embodiment of the present invention, the measurement data can be obtained, edited and transmitted, for instance, as follows. [0385] In FIG. 39, an operator starts creating a new measurement record 301A by the data logger 56 (Step S201). [0386] The operator measures the tires 24 and 25 by the pressure gauge 11 and the depth gauge 12 (Step S202), and transmits the measurement data to the data logger 56 when the measurement data is obtained (Step S203). [0387] After transmitting one measurement data, the operator checks whether the data logger 56 has received the measurement data (Step S204). [0388] If the measurement data has not been received, the operator transmits the measurement data again (return to Step S203). [0389] If the measurement data has been received, the operator checks whether the measurement data displayed on the data logger 56 is acceptable (Step S205). [0390] If the measurement data is abnormal, the operator confirms measurement validity by re-measuring etc. (Step S206). [0391] If the measurement data is acceptable, the operator continues the measurement, i.e. repeats Step S202 to S206 for predetermined number of pressure value and tread depth (inside, middle, outside) to finish obtaining measurement data (creating a new measurement record 301A) (Step S207). [0392] The operator starts the data storage terminal 57 (Step S208) and transmits the measurement record 301A from the data logger 56 to the data storage terminal 57 (Step S209). [0393] When the measurement record 301A is received by the data storage terminal 57, data processing such as storing in the database D2, printing or exporting is carried out (Step S210). [0394] According to the present embodiment, the same effects as the effects 1 to 14 (except the effect 4) of the first embodiment can be obtained and a following effect can be obtained. [0395] (Effect 15) The measurement data is temporally saved in the data logger 56 and stored in the database of the data storage terminal 57. Accordingly, the data logger 56 can be portable type, so that mobility can be improved. Further, the data storage terminal 57 is not required to be portable, so that the data storage terminal 57 can be standard desktop type. [0396] [Third Embodiment]
[0397] The present embodiment is basically the same as the first embodiment and different with respect to the followings in order to be suitable to promote a replacement component etc. to a customer. [0398] A tire model table 350D (not shown) corresponding to the tire model table 350 of the first embodiment includes data 3051D, 3501D to 3507D respectively corresponding to the data 3051, 3501 to 3507 of the table 350 and further includes price information 3508D of each tire and delivery 3509D of replacing a tire. [0399] A screen displaying function 890 corresponding to the screen displaying function 390 of the first embodiment includes display screens P81 to P86 (not shown) respectively corresponding to the display screens P11 to P16 of the first embodiment and further includes a replacement tire list displaying screen P87 (FIG. 40) for displaying a list of a suitable replacement tire to the vehicle displayed on the display screen P81. [0400] On the screen P81 corresponding to the screen P11 of the first embodiment, a command buttons displaying field F815 corresponding to the command buttons displaying field F115 has a replacement tire list displaying button B8101 to display the screen P81. [0401] The screen P87 includes a replacement tire list displaying field F871 to display item code, manufacturer, model, width, size, ratio, speed, type, price and delivery of a suitable replacement tire to the vehicle displayed on the screen P81, a print button B8701 to print a replacement tire list 880 for displaying customers displaying data of the field F871 with predetermined data, and a cancel button B8702 to close the display of the screen P81. [0402] The tire list 880 is given to the customer to make a choice at home if a replacement tire cannot be selected on site. [0403] As shown in FIG. 41, the tire list 880 has a quotation number displaying field F881 to display a quotation number, a replacement tire list displaying field F882 to display information of a replacement tire, a customer's procedure displaying field F883 to display customer's order procedure, and a contact address displaying field F884 to display a contact address. [0404] The field F881 shows an identified number to identify the tire list 880. [0405] The field F882 displays data corresponding to the field F871 of the aforesaid screen. [0406] The field F883 shows order procedure for the customer who has taken the tire list 880 and decided to replace a tire. For example, after selecting a replacement tire, the customer should contact with the contact address displayed in the field F884 and tell the quotation number displayed in the field F881, identification data (item code, manufacturer, model) to identify a replacement tire selected from the field F882 and date when the customer comes to the shop. Then, the customer should confirm stock or delivery of the replacement tire and come to the shop. [0407] The present embodiment includes functions 891 to 899 corresponding to the functions 390 to 399 of the data processor 39 of the first embodiment and further includes a replacement tire list displaying function 89A to display a list of a suitable replacement tire to the vehicle displayed on the screen P81. [0408] The function 89A is performed based on the following process. [0409] When the button B8101 is clicked on the screen P81, the screen P87 for a suitable tire list to the vehicle is displayed overlapping with the screen P81. [0410] When the print button B8701 is clicked on the screen P87, the tire list 880 is printed out. When the cancel button B8702 is clicked, the screen P81 is displayed. [0411] Since the third embodiment except the above content is the same with the first embodiment, specific description will be omitted. [0412] According to the present embodiment, the same effects as the effects 1 to 13 of the first embodiment can be obtained and following effects can be obtained further. [0413] (Effect 15) The list of the suitable replacement tire list to the target vehicle can be displayed. Accordingly, even if the operator has a little knowledge of the replacement tire, the business can be smoothly proceeded. [0414] (Effect 16) The replacement tire list includes the delivery information for replacing tire. Accordingly, the business can be preceded furthermore smoothly as more information to decide replacement is provided to the customer. [0415] (Effect 17) The replacement tire list as a document for the customer can be printed out. Accordingly, the customer can take the list to the home without placing the order for the maintenance operation on site, then consider the order later, so that customer service can be improved as providing extra time to consider, and the dealer can increase the possibility of receiving an order later even when the dealer doesn't receive an order on site, so that sales opportunity can be increased. [0416] [Modifications]
[0417] Incidentally, the scope of the present invention is not restricted to the above embodiment, but includes modifications and improvements as long as an object of the present invention can be achieved. [0418] For example, although the wireless communication is used as a communication method in the embodiment, radio wave, infrared light etc. can be used as a concrete wireless communication method. Further, not only the wireless communication but also wired communication can be employed. [0419] Although the pressure gauge and the depth gauge as the wheel gauges are used as the measuring instruments in the above embodiment, other wheel gauges such as a hardness tester or a surface roughness gauge can be used, and wheel periphery measuring instruments such as an electronic calliper for measuring a brake pad or a brake shoe and a light permeability test gauge for measuring a brake fluid can be used. Furthermore, the pressure gauge, the depth gauge and the other measuring instruments may be combined together. [0420] When the aforesaid measuring instruments are replaced or added, the present invention can be easily implemented by reflecting replaced or added measurement items to the measurement records, the displayed screens and the operations. [0421] Although the note computers are used as the data processor or the data storage terminal, the computers can be other computer such as a desktop computer. A notebook computer etc. can be used as the data logger instead of the so-called PDA, or the other data input devices such as a specialized input device can be used. However, wide-purpose devices and software may preferably be used to execute the functions of the present invention. [0422] Although the database is set in the data processor, the database can be separated into a database storing device and the data processor as a file server and a processor. [0423] Although the wireless receiver of the data processor is the PCMCIA standard card, an arrangement which the wireless receiver is built-in or which other external device is externally connected through RS232C port or so can be employed. [0424] Although the measurement data is received from the pressure gauge and the depth gauge in turn, the measurement data may be received from only one of them or may be simultaneously received from a plurality of gauges. [0425] Although the measurement data includes the tire pressure and the tread depth of the tire, the measurement data may include other measurement value such as rubber hardness of the tire or surface roughness of the tire. Further, the tire pressure, the tread depth and the other measurement value may be included together. [0426] Although the tread depth is measured on three points of inside, middle and outside in width direction of the tread surface of the tire, the tread depth may be measured on less than or more than three points. Further, points of the tread depth may be processed as data block to display a tread surface profile. [0427] Although the input order of the measurement data into the data processor or the data logger is set in advance, the order may be changed by the operator. [0428] Although the measurement data of the plurality of the tires of one vehicle is displayed on one screen, measurement data of a plurality of tires of a plurality of vehicles may be displayed on one screen. [0429] Although the measurement data is displayed in the figure representing the positions of the tires, the measurement data may be displayed by other method. [0430] Although the bar graph coloured corresponding to the measurement data is displayed, other graph such as a monochrome graph or a circle graph may be displayed. [0431] Although the display screen of the data logger has the input fields, the check boxes and the command buttons in addition to the characters, only text data may be displayed or the same display screen as in the data processor may be displayed. [0432] Although each tire gauge is identified with the transmission ID, channels can be used to identify the tire gauges. Further, the combination of the measuring instrument and the data receiver may be optionally changed. [0433] Although aforesaid embodiment is explained in basis that the number of the tires of the measurement table is restricted, extra tire may be added. [0434] Although the measurement record is identified with the vehicle registration number and the measurement date/time, the measurement data may be identified with other method such as using the customer's name. [0435] Although the measurement record includes the measurement data group, the vehicle data group, the customer data group and the tire data groups, other data may be included or some of the above data groups may be excluded if the measurement data is included. [0436] Although the measurement data is stored in the data processor or the data logger, the measurement data may be stored in the measuring instrument itself. [0437] Although the newly created data or the stored data in the data logger is edited in the data logger, data loaded from the data storage terminal may be used in the data logger. [0438] Although the maintenance operation is the replacement of the tire, the maintenance operation may be other operation such as replacement of a brake pad. [0439] Although the data for the replacement tire includes the item code, the manufacturer, the model, the width, the size, the ratio, the speed, the type, the price and the delivery information for replacing the tire, the data for the replacement tire may include other promotion information such as features of each replacement tire or an image of tread pattern of each replacement tire.
