Regular Driving Tire Pressure

There's lots of talk on track tire pressure but what are you guys running on the street or for regular driving? I'm at 34psi cold (this is where it was set from the dealer) and 38psi after they warm up. I received a diagnostic from onstar and they said the tires should be at 32psi.

I'm interested in this. Used to run 38. Worked well for quite a while. At some point picked up a shimmy at about 65ish which appears somewhat common. After searching for solutions on the forum I went up 5psi to 43 and it helped. It is still below max inflation pressure for my tires so I've been sticking with it for 5-6 months so far.

30-32 cold is perfect. Higher pressures will beat you to death! I consider 34 psi cold too high.

I agree with Stephen12ZL1. 32psi, I do store it with 35 to 38 psi.

Tires pressure has to be checked? LoL... I had mine changed out to nitrogen when I had a valve stem seal go bad. Put them at 32 and have not had a issue again. Guess that has been 5 or 6 months ago. When I change out the rears I will go back to air because I will be adjusting the pressure a lot when I will be racing.
