Why does it not surprise me that you would say this... Really??? Where did i state street compound tires can run perfectly fine at the track all day??? Now your putting words in my mouth. Don't make an ass out of yourself by assuming. So race compound tires do not heat up the same as street tires huh... I guess the head guy of Pirelli USA is talking out his ass when he specifically said and his words printed; RACE tires heat up just as quickly as street tires, and the myth they do not is just that a myth! Now i just find this statement you made as absurd as possible. Street tires have a compound structure that allows them to work great at street pace but Race tires don't. Are you serious, what structure might that be??? LOL, come on bro now your just trying to catch without bait. The only statment you made up there that makes sense is Just much longer well that is what im disputing with you. It does not take that much longer for them to heat up. In fact the difference is so insignifcant the top guy at Pirelli called it a Myth.My original response was to his original statement so maybe i should have read the entire thread but my advice is far from bad.
