Hi What tyre pressure do you run with the 348 challenge wheels on 285x35x 18 and 225x40x 18 Thanks Tom
You run the tire pressures that allow you to come off a hot lapping session, stop immediately in the pits without a cool down lap, and measure the tire temperature at 200ºF. But let me be more specific: When the average across the profile is at 200ºF, and the center is the same as the average outside and inside, you have found the correct tire pressure. Race tires are funny like that.
