    Driving school tire pressure recommendations

    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.

    Thanks so much and happy Easter to everyone,

    Jim

    You should be running at least 40lbs on street tires. Check on line with your tire manufacture as they should have warnings / cautions about hi speed driving.


    Have fun!

    Get a tread depth gauge and some tire marker. Start at about 35 cold and watch those outer front shoulders like a hawk.

    Bump up if needed...

    I ran 37 PSI cold in the front and 35 PSI cold in the rear. No wear at all on shoulders. I will write a quick review of the driving school and post it on a separate thread.

    Thanks for all the input,

    Jim

    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.

    I rant 40-38 cold, because I didn't want to destroy my tires. It worked out well.

    I should have added that I also have the 275/35x19 Michelin Pilot Super Sports up front, and stock size in the back.
