MPSC tire pressures "live" from Michelin
I spoke today to the person who handles MPSC tires at Michelin. It was like Pirelli, a nice guy who was most helpful. He said what made more sense to me and contradicts Michelin's 2003 Powerpoint presentation that has been posted here on Rennlist for a 996 on the track. He wanted to know my set up, weight, etc., so the following only applies to what you see in my signature. Depending on ambient temperature:
Start with Cold: front 25 to 26 psi. Rear 26 to 27 psi. End with Hot target: front: 32 to 33 psi; rear 34 to 36 psi. He also gave tire temperatures taken from 2 to 3 inches from the edge to the very edge, hot with no cool down lap: 160 degrees to 220 degrees, with 180 to 200 degrees being best.
