i searched and could only find 1 thread about aftermarket wheels.. im wondering how much psi you guys are running your aftermarket wheels/tires.. im currently running 33-35 psi all around on my 255/35/19, 275/35/19.. max psi on my rear tires says 54psi.. how much air do you guys think i should have in it?

I think you're running it a little low. I run 36-38 psi on mine and I have 18" tires...

its reccomended to stay between 36-38

When I get to 35psi I feel that's a bit too low. I agree with the above. Between 35-40 seems ideal.

when you guys are going to run a 1/4 mile on your street tires? what do you keep your psi at? do you leave it high at like 38? or do you drop it? just curious...

When I went to the track I dropped them to 20 psi. don't know if it made a diffrence.

definately drop the psi to 20 or under if you want when u're at the 1/4 track. it does help get you out the hole faster

Recommended cold tire pressure all around for the car is 35 PSI. I have the Nismo 18s with Falken RT-615s and still run them at this pressure (actually 34 in the rear) and it feels good. When driving, they are in the 38-40 range.

hmm lets keep this going guys..
my fronts when cold are at 34psi when it heats up it goes to 35.5-36.5 psi
my rears when cold stay around 32.5-33.5psi and when hot they go to 34.5-35.5psi (will add some psi tomorrow)

question - at what psi does it get dangerous for the wheels to get bent/damaged?
