I'm new to club racing, but have run a lot of HPDE. I tried to search the forum for this question but had no luck. The IT rule for tires is "Any DOT-approved tire is permitted. Racing, recapped, or regrooved tiers are not allowed. Tire size in unrestricted. The only modifications allowed to tires are having treads "shaved" or "trued."
So, if I understand correctly, both R-compounds (eg, Nitto NT-01, Toyo RA-1 and R-888), and competition slicks (eg, Hoosier R6, Kumho Ecsta V710) are allowed.
Is that correct? If so, does everyone run slicks rather than R-compounds in dry weather? Thanks!
