C6, running ZO6 size Supercars (325s and 275s). Did a search and couldn't really come up with an answer. Cold pressure, and hoped-for hot pressure?

Thanks!

Try starting out with the recommended pressure that are listed on your door.

AU N EGL

Normal Cold pressure is what 32 psi?

But that is for NORMAL driving. and no not normal track

Tire pressure is individual to the driver.

Starting out 30 psi front and 28 psi rear cold

and then should go up 10 psi or so to 40 and 38 psi. which may be too much.

IIRC the alarm goes off at 42 or 44 psi.

Mid to upper 30s HOT would be a good starting place to aim for for the GYs

You clearly need to start out lower than "normal" pressure easily goes up 10 psi in the summer on a heavily loaded front tire (left front at Summit Point).

My experience is that when it gets over 39 psi it really turns to a crap tire.

I start out at 26 fronts and 28 rear, and target 36 for all at the end of the run.

Key is to measure the pressures at the end of your session.

also depends on how hard you are driving and how much brake heat is going to the rims. New be I would add 2 pounds to the door pressure in front. and check from there. Rough start.

That's what I was thinking we had run at the Roval, but I sure wanted to make sure before I got out on track with these.

Thanks very much!

Hot tire pressure is the key. I like 40 psi - others like 36 psi. Keep very detailed records of every session. You should have a notebook.
