I plan to run a couple track days this year at 2.5 track near me. They repaved it this past summer. My question is what tire pressure should I run. I have a 2020 LT RS V6 with the 245/40 20 All Season run flat tires. A l-o-n-n-g time ago when sidewalls were much taller we'd pump those babies up at 5 pounds over when they were cold.

I have those same stock tires on my RS V6. All I know is that changing pressure had no effect at the dragstrip

30psi is usually a good starting point for a street tire.

You probably want to end up somewhere in the 35 - 37 psi range HOT.

Don't be afraid to try 2 or 3 psi front to rear inflation pressure stagger, either. Especially with a 'square' wheel and tire setup.
