Couldn't really find much in previous posts. For those of you running the Michelin PS ZP's at the track, what starting pressures have you been using? I don't have the tire temperature gauge thingy, generally been going by feel and edge wear - admittedly lacking science.

FWIW, this is my second set of these, been through the stock GY's, Bridgestone Pole Position RF's, then these, and these are by far my favorite for street/track compromise.

Dragracing or road track or auto crossing? If auto crossing or road racing put soom chalk marks across the thread-sidewall area and add or decrease air accordingly.

I believe at spring mountain they had all these tires around 38. This was hot pressure. Not 100% sure on the cold setting.

AU N EGL

2 psi less then stock COLD to start.
