Lapping Tire Pressure
I'll be doing some lapping again at the Shannonville Motor Sport speedway. I was wondering, if the ambient temp. is 70 degrees, what is a good recommened tire pressure for 20 minute lapping sessions with the stock F1's ?

Cold tire pressure 35 psi Hot 38-40 psi - Hot meaning just after your run.
Most tires go up 3 to 5 psi depeding on the ambent temp.

Just watch the side ot the tire. You want the whole tread involved but not rolling up the sidewall.
It's great to see questions like this rather than "how many coats of Zaino do you have on!"?
