In Response to Wheel Width #31849
#31913 from Timothy White · Not recommended · Minutes (2023-01 Fastrack)
Thank you for your letter. Regarding the rim width rule change, which primary focus was to increase tire life, we have received a
lot of feedback that tire life has been extended. In most cases where tires are being used for many events the increased tire life
has been well received. Tire manufacturers recommendation for rim width was used to determine the max rim width with a plus
.5 inch tolerance, recognizing availability may be limited, and some cars may not be able to utilize the maximum allowable rim
width.
