I was running my Toyo T1-R 215/45 17s at 40 psi from cold at the front and rear. I tried a couple of track days at 34-36 but destroyed the shoulder of the tyre so was advised to run as hard as I could - hence the 40 psi.
Once up to temp I bled the tyres down to 40 again and carried on.
Can't say that this helped any - check out the pics
So that'll be two new tyres again then will it?
