Street tires are made of a compound that will stay pliable longer than R tires. The oils in the tires do not evaporate as quickly because they have longer tread life. I just sold a set of VictorRacers for $25 and they were 4 years old. Those were hard as super balls.

Right which makes a lot of sense, since these guys are on the track for 30-45mins going balls out. But that is exactly what makes them hard as balls and not as sticky as street rubber that has several autox on them.

And autocrossing is not as abusive in some aspects on tires as road racing. Autocrossing you are cornering for about 5-10 seconds maybe? Road racing you are cornering for twice as much as twice the speed with more forces acting upon the car than an autocross car.

I know my autocross pressures go up about 2-5 psi. When I did a track day my tires went up 10-15psi on one session.

i just pit crewed last weekend for a 944 cup race team and their tire pressures were up 8-10 psi on the left side while only 5-6 psi on the right side as summit point is a clockwise track...we wound up lowering pressure of cold tires on the left to have more even handling throughout the race
