Tire Pressure Help Needed - Michelin PS Cup 2
First track day with the Z51 Stingray coming up in a little over a week at Buttonwillow. Anyone have cold and hot tire pressure suggestions for Michelin Pilot Sport Cup 2?

If you're driving hard, start at 26-28 psi cold and aim for 32-36 hot. Above 38 they get unhappy. They can easily rise 10psi when driven aggressively.

OM states to start with 26 cold but if you are running a Z51 with those tires I would probably start at 28 and then adjust in 1 lb increments up or down between sessions to resolve any handling issues I noticed during a session.

I run RE71 on my Z51. I start out at 26, and by end of the session I am around 35. 28 was too much especially in the rear, got twitchy. The Cup2 and RE71 do not stick well when cold so don't push it too hard in the first lap or so.
I run with the TPM display all the time, even on the street. I find the TPM to be quite accurate.
