Patent ID: 6917894

Claim:
A tire plus-sizing computer program product comprising a medium readable by a processor, the medium having stored thereon: (a) a first sequence of instructions which, when executed by the processor, causes the processor to display a screen having input boxes for receiving data input by a user identifying an original equipment tire size and identifying a desired wheel size; (b) a second sequence of instructions which, when executed by the processor, causes the processor to access a database record for the original equipment tire size and to display a tread width, sidewall height, and overall height stored in the record; (c) a third sequence of instructions which, when executed by the processor, causes the processor to retrieve a plurality of database records for tire sizes having a wheel size equal to the desired wheel size, an overall height within a range of 3% less than the original equipment tire size overall height to 3 greater than the original equipment tire size overall height, and a tread width within a range of 15% less than the original equipment tread width to 15% greater than the original equipment tire size tread width; (d) a fourth sequence of instructions which, when executed by the processor, causes the processor to sort the records retrieved in the third sequence in order of decreasing overall height; and (e) a fifth sequence of instructions which, when executed by the processor, causes the processor to select and display up to three tire sizes from the sorted records having an overall height closest to the overall height of the original equipment tire size.
