I know this is a little off topic but I saw a set of cup 2s on the rear on an AMG coupe convertible yesterday at Sonoma that were worn past the 2 deep tread grooves after just 4 sessions. They started the day with just some normal street wear according to the car owner and the fronts would somewhat attest to that. He knew he was running too much air in them (adding to the fact it's a heavy 550hp front engine car.) I guess this would come under "too much heat" cycles.

Yeah, you gotta watch your hot pressures and keep them at a moderate level. Also, a good cool down lap is important for both tires and the engine/tranny/brakes.
