Request adding 7.5
#29582 from Corry Hunter · Not recommended · Minutes (2021-02 Fastrack)
Thank you for your letter. Under GCR 9.1.3.7, IT wheel and Tire rules. Wheel sizes listed are maximum sizes with their
corresponding maximum section width. In ITS a 7.5" wheel is already permitted and would fall under the 8" maximum rim width
with a maximum section width of 225. The purpose of the regulation is to limit the advantage of a wider wheel. We do not
recommend a change to this regulation at this time.
