I'm attending a high performance driving school at Putnam Park next weekend. I have brand-new Hankook Ventus V12's (275/35/19 and 305/30/19 with 10 mm spacers all the way around). My Michelin PS2's gave me 17,000 miles plus. However, the outside of each tire particularly in front were perfectly smooth.
I know the idea is to keep the tire pressures high enough that you don't hand over onto the outside of the tire in turns. The tires' maximum tire pressure is 50 psi, which I understand is in fact the cold temperature rating.
I think I should start out at about 37 psi and 35 psi – cold – and see what happens. However, I would appreciate advice from smarter people than me or maybe people with more experience so I don't hurt my own feelings.
I left them at 32 cold, and watched them go up during the driving to 35-ish. I like that better than starting higher. When I started higher, they shot way up, and I got the high-pressure warning. No rolling over either at the lower pressures.
