Am instructing in a GT3-RS next week, just found out. P-zero Corsa's are on the car. Can anyone tell me a hot pressure to use and being totally unfamiliar with that tire a starting point cold?
Lets say it is 55 degrees in the morning next week at Thunderbolt. I have an '04 GT3 with MPSC tires I like at 31.5 and 34.
To get that I would probably start the day at 25 and 27 and tweak after the first session, undoubtably letting air out.
would P-Zero's like more or less?

Also, I have a student with an Exige. Working on figuring out his tires too. Anyone have experience in a Lotus and want to suggest tire pressures for what rubber they have??

 

Corsa likes a few pounds more. On my track, 34F 36R Hot works best.

 

Send me a pm with your email I will send you a PDF on the corsa and what the MFG recommends. But I agree with Bob I ran a set of Corsa's all last year, 34-36 is the exact pressure i ran good grip good wear. the MFG says 30 hot because it has a stiff sidewall but I did not like it.

 

Thanks guys. I'll suggest a cold temp to end up at 34/36 hot. Should be close enough really with the RS being new to the owner etc.
No one out there running an Exige who can suggest temps for whatever tire they run?
