Hey there, I have 35x12.50x15 Cooper STT Pros and was curious to know if there’s a certain air pressure I should run them for proper wear. I’ve been running them at 28-30 but wanted to know some other opinions on it. Thanks.

I run my 35" MT/r at 25 psi. I can't speak much for wear though since I only drive around 2k a year on them.

28-30 for a 31"
26-28 for a 33"
24-25 for a 35"

24-28 psi. If in doubt, you can always to a chalk test. However, anything over 28 psi is likely too much.

I like your avatar. Jeep looks awesome. Maybe I just like me some cut hood and those hi-lines. BA
Thanks! From 20' it looks good. Up close my paint on the fenders is really starting to peel/rust. I need to strip and repaint them.

It's a Jeep! I need to fix rust daily. I've been thinking about doing my gas tank skid (again)!

Mid 20’s is what I ran on 35’s and on my 37’s. I’m not too picky when it comes to exact pressure but will make sure there all the same

That seems low for those tires, they are supposed to run on the center treads only down the road. At least that’s what I heard on YouTube.
That's what LiteBrite told us for their JLU. Take that for what it's worth.
