1. What tire pressure do I run? 2. What are the compounds and how do I know which compounds go with the SC #s? 3. What is the difference between street and race tires? |

Good Question! In the race compound tires, in other words anything with an SC and a # should be around 29 psi in the front and around 25 psi in the rear, cold, before you go out on the track. If you have tire warmers you can set the tire pressure hot, this is a better way of doing it. Hot, after an hour on the warmers, should be 32 psi front, and 28 psi rear. Whether you are using warmers or not, right after you come off the track and the tires are hot, the front should be between 32-33 psi and the rear should be between 28-30 psi, if they are low add pressure, if they are hot remove pressure. Diablo Corsa 3s should be set cold at 32 psi front and 30 psi rear. Rain Tires and Wets should be set at 32 psi front and rear cold. back to top |

Well, it?s quite simple really, the lower the number the softer the tire, 0 being the softest and 3 or 4 being the hardest. As far as compounding goes a 0 would be an extra supersoft, 1 a supersoft, 2 a soft, 3 a medium, and 4 a hard. There are also color codes used, White = 0, Blue = 1, Green = 2, Yellow = 3, and Orange = 4. back to top |

Quite simply everything. Although street tires are more advanced every year and are starting to share a lot of properties from race tires..ie weight, carcass, rubber family ect there is still a huge difference. Race tires are constructed with the most amount of heat and abuse you could dish out in mind. They are designed to work better when more heat can be put into them. Street tires are designed to have good wear and a lot of heat cycles. Meaning they dissipate heat rather than holding it in like a race tire. Street tires tend to get worse the more you abuse them. The theory is more traction faster wear, longer wear less traction. back to top |
