Experiment for the exact pressure based on wear, but I bet you end up right about 30 psi

Bondurant in is book on driving suggests starting with the cars weight divided by 100, then adjust up or down from there. Pretty close to 30 psi.isn't it?

your have low profile tires. your wheels will bent if you dont have enough tire pressure. I have 295/30/20 and my wheels used to get bent after hitting a pothole when i had 30psi. i keep 35 psi cold all around now, no problems

Sounds like Michigan roads!!! Don't think so? Check out our roads in the Spring, and double up on Dentu Creme, if you have dentures!! I had all 4 wheels bent on my 2014 CTS Cadillac!! That's not cheap wheels, it's physics! Put a 25 or 30 series tire on a 19" or 20" wheel, with a 2-1/2"-3" sidewall, hitting a Michigan pothole=NEW WHEEL TIME
