Reply to "Tire PSI"

By the way,

Assuming your toe in and camber are set properly, you'll want to run enough air pressure to achieve even temperatures across the face of the tire, at least as a starting point for a track setting.

On a street car, the best setting will be the pressure that achieves even wear across the tire. Too much pressue will cause the tire to wear faster in the center, too little pressure will cause the tire to wear faster on both edges.

I'm running close to the factory recommended setting, i.e. 28 psi front, 26 psi rear. One end (the rear I think) is running about a pound less pressure than the factory recommendation, due to wear.

The pressures that work best on the street will likely be inadequate on the track.
