         1.   SCOPE
   This Regulation covers new pneumatic tyres designed primarily, but not only, for agricultural and forestry vehicles (power-driven vehicles in category T), agricultural machines (power-driven and trailed) and agricultural trailers, and identified by speed category symbols corresponding to speeds of 65 km/h (speed symbol ‘D’) and below.
   It does not apply to tyre types designated primarily for other purposes, such as:
   
               (a)
            
            
               Construction application (tyres marked ‘Industrial’ or ‘IND’ or ‘R4’ or ‘F3’);
            
         
               (b)

               Except as provided by paragraph 6.1.2, the section width is calculated by the following formula:
               S = S1 + K (A – A1)
               where:
               
                           S
                        
                        
                           is the ‘section width’ expressed in mm related to the measuring rim;
                        
                     
                           S1
                        
                        
                           is the ‘nominal section width’ in mm as shown on the sidewall of the tyre in the tyre-size designation as prescribed;
                        
                     
                           A
                        
                        
                           is the width (expressed in mm) (3) of the measuring rim, as shown by the manufacturer in the descriptive note,
                        
                     
                           A1
                        
                        
                           is the width (expressed in mm) (3) of the theoretical rim; it is taken to equal S1 multiplied by the factor X as specified by the tyre manufacturer and
                        
                     
                           K
                        
                        
                           is taken to equal 0,4.
                        
                     
         
               6.1.2.
            
            
               However, for the types of tyre for which the size designation is given in the first column of the tables in annex 5, the theoretical rim width (A1) and the nominal section width (S1) are given opposite the tyre size designation in those tables.
            
         6.2.   Outer diameter of a tyre
   
               6.2.1.
            
            
               Except as provided by paragraph 6.2.2, the outer diameter of a tyre is calculated by the following formula:
               D = d + 2 H
               where:
               
                           D
                        
                        
                           is the outer diameter expressed in mm,
                        
                     
                           d
                        
                        
                           is the conventional number denoting the nominal rim diameter expressed in mm (see paragraph 2.16),
                        
                     
                           H
                        
                        
                           is the nominal section height in mm and is equal to:
                           H = 0,01 × Ra × S1
                        
                     where:
               
                           Ra
                        
                        
                           is the nominal aspect ratio,
                        
                     
                           S1
                        
                        
                           is the ‘nominal section width’ in mm
                        
                     all as shown on the sidewall of the tyre in the tyre-size designation in conformity with the requirements of paragraph 2.15.
            
         
               6.2.2.
            
            
               However, for the types of tyres for which the size designation is given in the first column of the tables of annex 5 the outer diameter (D) and the nominal rim diameter (d) expressed in mm are given opposite the tyre size designation in those tables.
            
         6.3.   Tyre section width: specification of tolerances
   
               6.3.1.
            
            
               The overall width of a tyre may be less than the section width determined pursuant to paragraph 6.1, or shown in annex 5;
            
         
               6.3.2.
            
            
               The overall width of a tyre may not exceed the section width determined pursuant to paragraph 6.1 by more than the following:

         6.4.   Tyre outer diameter: specification of tolerances
   
               6.4.1.
            
            
               The outer diameter of a tyre must not be outside the values D min and D max obtained from the following formulae:
               D min = d + 2 (H × a)
               D max = d + 2 (H × b)
               where ‘H’ and ‘d’ are as defined in paragraph 6.2.1.
               
                           6.4.1.1.
                        
                        
                           for sizes listed in annex 5: H = 0,5 (D – d) (for references see paragraph 6.2 above).

               6.5.1.
            
            
               The actual dimensions of tyres are measured as prescribed in annex 6.
            
         
               6.5.2.
            
            
               The test procedure to assess the resistance of the tyre to burst is described in annex 8.
               
                           6.5.2.1.
                        
                        
                           A tyre which, after undergoing the relevant test to assess the resistance to burst, does not exhibit any tread separation, ply separation, cord separation, broken beads or broken cords is deemed to have passed the test. The tyre tested shall not be used for any other tests.
                        
                     
         
               6.5.3.
            
            
               The test procedures to assess the suitability of the tyre for the claimed performances are described in annex 9.
               
                           6.5.3.1.
                        
                        
                           A tyre which, after undergoing the relevant load/speed test, does not exhibit any tread separation, ply separation, cord separation or broken cords is deemed to have passed the test. The tyre tested shall not be used for any other tests.
                        
                     
                           6.5.3.2.
                        
                        
                           A tyre which, after undergoing the relevant load/speed test, does exhibit chunking, due to the specific test conditions is deemed to have passed the test.
                        
                     
         
               6.5.4.
            
            
               Where a tyre manufacturer produces a range of tyres it is not considered necessary to carry out tests on every type of tyre in the range.
            
         7.   MODIFICATION OF TYRE TYPE AND EXTENSION OF APPROVAL
   
               7.1.
            
            
               Every modification of a tyre type shall be notified to the administrative department which approved the tyre type. That department may then either:
               
                           7.1.1.
                        
                        
                           Consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the tyre still meet the requirements; or
                        
                     
                           7.1.2.
                        
                        
                           Require a further test report from the technical service responsible for carrying out the tests.
                        
                     
         
               7.2.
            
            
               A modification of the tread pattern of the tyre shall not be considered to necessitate a repetition of the tests prescribed in paragraph 6 of this Regulation.
            
         
               7.3.
            
            
               Confirmation or refusal of approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 5.3 above to the Parties to the Agreement which apply this Regulation.
            
         
               7.4.
            
            
               The competent authority issuing the extension of approval shall assign a series number for such an extension and inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in annex 1 to this Regulation.
            
         8.   CONFORMITY OF PRODUCTION
   The conformity of production procedures shall comply with those set out in the Agreement, Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev.2), with the following requirements:
   
               8.1.
            
            
               The pneumatic tyres approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraph 6 above.
            
         
               8.2.
            
            
               The authority which has granted type approval may at any time verify the conformity control methods applied in each production facility. For each production facility, the normal frequency of these verifications shall be once every two years.
            
         9.   PENALTIES FOR NON-CONFORMITY OF PRODUCTION
   
               9.1.
            
            
               The approval granted in respect of a type of pneumatic tyre pursuant to this Regulation may be withdrawn if the requirement laid down in paragraph 8.1 above is not complied with or if the tyres taken from the series have failed to pass the tests prescribed in that paragraph.
            
         
               9.2.
            
            
               If a Party to the Agreement which applies this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties which apply this Regulation, by means of a communication form conforming to the model in annex 1 to this Regulation.
            
         10.   PRODUCTION DEFINITELY DISCONTINUED
   If the holder of an approval completely ceases to manufacture a type of pneumatic tyre approved in accordance with this Regulation, he shall so inform the authority which granted the approval. Upon receiving the relevant communication that authority shall inform thereof the other Parties to the Agreement which apply this Regulation by means of a communication form conforming to the model in annex 1 to this Regulation.
   11.   NAMES AND ADDRESSES OF TECHNICAL SERVICES RESPONSIBLE FOR CONDUCTING APPROVAL TESTS, OF TEST LABORATORIES, AND OF ADMINISTRATIVE DEPARTMENTS
   
               11.1.
            
            
               The Parties to the Agreement which apply this Regulation shall communicate to the United Nations Secretariat the names and addresses of the technical services responsible for conducting approval tests and, where applicable, of the approved test laboratories and of the administrative departments which grant approval and to which forms certifying approval or refusal or withdrawal of approval, issued in other countries, are to be sent.
            
         
               11.2.
            
            
               The Parties to the Agreement which apply this Regulation may use laboratories of tyre manufacturers and may designate, as approved test laboratories, those among them which are situated on their territory or on the territory of another Party to the Agreement subject to a preliminary agreement to this procedure by the competent administrative department of the latter.
            
         
               11.3.

                  Agricultural steering wheels tyres are identified either by suffix ‘Front’ placed after the Tyre size designation (e.g. 4,00 - 9 Front) or by one of the following additional markings added to the Tyre sidewalls: ‘F–1’ or ‘F–2’.
               
            
                  2.
               
               
                  Tyres of radial structure are identified by means of the letter ‘R’ in place of ‘-’ (e.g. 4.00R9)

                  The Tyre size designation may be suplemented by an additional figure: ex: 23,1/18 - 26
                  instead of 23,1 - 26.
               
            
                  2.
               
               
                  Tyres of radial structure are identified by means of the letter ‘R’ in place of ‘-’ (e.g. 23.1R26).

                  Tyres of radial structure are identified by means of the letter ‘R’ in place of ‘-’ (e.g. 205/50R10)
               
            
                  3.
               
               
                  Overall diameters (D) in column (*) apply to tyres marked with classification code ‘I 3’ — see paragraph 3.1.8.2.

            Notes:
      
                  1.
               
               
                  These Tyres may be classified in categories of use ‘Tractor Drive Wheels’ or ‘Implement’.
               
            
                  2.
               
               
                  Implement Tyres are identified either by suffix ‘IMP’ placed after the Tyre size designation (e.g. 11×4.00 - 4 IMP)or by the word ‘IMPLEMENT’ marked on the Tyre sidewalls.
               
            
                  3.
               
               
                  Tyres of radial structure are identified by means of the letter ‘R’ in place of ‘-’ (e.g. 11×4.00 R 4).
               
            
                  4.
               
               
                  Coefficient ‘b’ for the calculation of the Overall diameter Dmax:
                  
                              (a)
                           
                           
                              1,12 for tyres with Nominal rim Diameter (d) less than 380 mm;
                           
                        
                              (b)
                           
                           
                              1,10 for tyres with Nominal rim Diameter (d) 381 mm and above.

         TEST METHOD FOR MEASURING TYRE DIMENSIONS
      
      
                  1.
               
               
                  The tyre shall be mounted on the measuring rim specified by the manufacturer and is inflated to a pressure specified by the manufacturer.
               
            
                  1.1.
               
               
                  To seat the beads do not exceed the inflation pressure marked on the tyre sidewalls.
               
            
                  1.2.
               
               
                  Having properly seated tyre beads on the rim, adjust the pressure to the value specified for tyre measurements.
               
            
                  2.
               
               
                  The tyre fitted on its rim is conditioned to the ambient temperature of the laboratory for at least 24 hours.
               
            
                  3.

                  The overall width is measured by calliper at six equally-paced points, account being taken of the thickness of the protective ribs or bands. The highest measurement so obtained is taken as the overall width.
               
            
                  5.
               
               
                  The outer diameter is determined by measuring the maximum circumference and dividing the figure so obtained by π (3,1416).

                  4.2.
               
               
                  Apply on the trailer a mass in order that each tyre be equally loaded with a test load corresponding to the load carrying capacity allowed for that tyre type at 15 km/h (see load variations in annex 7).
               
            
                  4.3.
               
               
                  Run the trailer at a constant speed of 15 km/h ± 1 km/h for 48 hours.
               
            
                  4.3.1.
               
               
                  Temporary interruptions are allowed, but they must be compensated by an additional run-in of 5 min for every 20 minutes of interruption.
               
            
                  4.4.
               
               
                  The tyre pressure must not be corrected and the test load must be kept constant throughout the test.
               
            
                  4.5.
               
               
                  During the test the ambient temperature shall be between 5 °C and 30 °C or at another temperature if the manufacturer so agrees.
               
            5.   EQUIVALENT TEST METHODS
