Recommended tire pressure for Thunderhill
 

So I'll be at Thunderhill this weekend and I'd like to get some idea of tire pressure there in this temperature.

I am running the Bridgestone S04 with stock suspension.

It'sgonna be fun!

lots of variables in tire pressure...weather, alignment and driving style being the most important? Without getting into tire temp's I like to use the sidewall rollover test....if your hot pressures are too high you will notice the sidewall might only be half or less used....drop pressures until the sidewall is being worn, but not too far...only the tread part...not the actual sidewall itself....

I have seen heavy powerful cars that come in with literally the tire name scrubbed off...that is SCARY....

I ran my bone stock FRS with stock tire pressures....then I dropped them later in the day and grip improved....

That's a great tip. Thanks!

different tires have different characteristic with different tire pressure, a general rule I would say keep all tires <38 psi hot. I run Rivals and its more stickier with 36 psi hot so I set 32 psi cold when I first arrived at the track and adjust after each session
