I'm wondering how high one should go with cold tire pressures for a 180+ mph, 2-3 mile test run (hypothetically speaking). I have SS 1LE wheels and tires, except the sidewalls are 35 aspect ratio, not 30, and of course the tires are rated 186+ (Y).

For normal driving, cold pressure is set to 32 psi, and I'm thinking even 35 cold might be too low for such a run, but not sure how high one actually needs to go, if anyone has firsthand experience or a link for a somewhat scientific calculation, please post
