My local track runs the the track backwards for the street car brawl events and the surface at that end is terrible. I launch my car at 4K and spin down the entire 1320 in every gear the surface is so bad. I’m sure my 8 year old tires and open diffs play a big role in that. The true street class that I want to run requires awd to run a “dot approved hard tire”. They don’t have a answer as to what tread rating they are looking to see. Anyone run a class with similar rules? If so what tires work best for you? Or what tires would you think best fit these rules?
