Once my 245/40/17 RS4s are toast I’m thinking of either 245 RT660s or maybe 245 AR1s. They are all around the 10” section width range. While I could go wider, I think having a slight stretch to the tire is really beneficial for track/Autocross in terms of minimizing tire deflection. I felt a noticeable difference in initial turn in when going from 255s on a 9” wheel to 245s on a 9” wheel.
