What tire pressure...

What psi do you run in your tires when you go to the track? If tire size matters I have 295/36/zr18 on my car. Just wondering what i need to drop it to.

If it's a regular radial it won;t work any better with less than 22-24psi at the lowest. It all depends on the width of your rim also. What you need to do is go to a "nice" concrete parking lot and do some holeshots with different pressure.
Slowly lowering until your marks are darker on the edges than in the center. And once you see a nice even contact patch thats the pressure that will work the best for you.
