Help Me Understand Tire Pressures For Autocross
So I set my tire pressures at 32psi last night for today's autocross in a 68º garage. The tires in question are Bridgstone Ponenza RE71's. It went from 60º on the morning runs to 75º on the afternoon runs. A lot of talking and mumbling back and forth regarding tire pressures in the afternoon. Since I'm not burning rice or driving a Porsche little of the mumbling applied. The 2005+ Mustang crowd, very well represented and kicking butt VS the Chebby guys didn't seem to care in the least about tire pressures that they were willing to share. Don't know were to start on this?
