Correct me if I'm wrong, but wheel size has nothing to do with recommended tire pressure right? This is the first time I've checked my tire pressure since I had my new wheels put on. According to the door, I should be using 33psi but what I found was FL: 34.5, FR: 36.5, RL: 38, RR: 37.5. Sorry for sounding like a newb but, is that a problem?

 

Tire brands/tire types can vary in pressure requirements. I'd use the 33 as a minimum and 40 as a maximum (35 seems to be pretty good for most cases). If you go much lower than 33 the TPMS light may go on, especially in cold temps. I would be sure to get all your tires within 1 psi of each other

 

Thanks newt. I was thinking I'd get all 4 to 36psi

 

You'll need at least the door jamb pressures to support vehicle weight properly. You also don't want to exceed the tires max psi mentioned on the sidewall. Anything between the two, tuned in a couple pound increments until you get the feel/handling you're after, will work fine.

 

^ That sounds like someone was trying to do the TPMS reset, and didn't inflate the tires after the procedure was done.

 

Yeah I think I found a sweet spot with 36psi front and 37psi rear. Any more than that up front and the vibration is unbearable

 

Shouldn't have vibration, did you install hub adapter rings w/ those new wheels?

 

I did install hub rings, and that's what I thought. But I did get vibration in the steering wheel. I deflated them to 36, thinking that shouldn't make a difference, but it did.
