Please Revisit Tire and Wheel Width Rule Letter #33728
#33936 from James Rogerson · No action required · Minutes (2023-04 Fastrack)
Thank you for your letter. There is no change to the original response to letter #33728, which requested that vehicles which are
specified to run a MAX 13" diameter wheel be allowed to run a 15x7" wheel when using the B-Spec Hankook or SM Hoosier
tire. It pointed at rule 9.1.5.E.8.c as justification to why this should be allowed. Rule 9.1.5.E.8.c allows for an increase in wheel
WIDTH only, when running a specific America Racer tire. It does not allow for an increase in wheel diameter, versus what is on a
vehicles spec line, which is not the same as what's being requested here. Furthermore, its existence alone is not enough of a
justifiable reason for the PAC to make further special tire and wheel package allowances, which are outside the scope of the
Production Category. If the goal is to just find a cheaper alternative than the radial or bias-ply slick tires that are common in
Prod, with competitiveness not being a concern, then a competitor is free to use a DOT race or street tire that fits their MAX

wheel size, as specified on their vehicles spec line.
