Tire pressure for the track
I'm going to the High Peformance Driving class given by Proformance Racing at Pacific Raceways. Their "form" letter says: "Tires should be over-inflated by approx 5-10 PSI over normal specs (i.e. 38 PSI front and 42 PSI rear, cold)." Of course, those numbers are for a normal passenger car.
I've seen mixed info on the forum about tire pressure at the track, autocross, etc.
I'm running Yokohama 245X45/17 front and 275X40/17 rear. For street use, I normally keep them at 26 PSI. Forecast temp on the day in question is about 75 degrees.
So, should I keep 'em where they are, air 'em up, or air 'em down?
