    What Is Your Favorite Air PSI For 35s Tires?

    What do you guys say about running 37?

    I currently have 22x12 -44 on 37 Toyo AT tires, and I'm currently running 57.

    I got the number from some tire calculator i found on here or another website.

    If I remember correctly, it took my stock rims/tires size and then my new rims/tires size, and then it gave me 57psi.

    I would like to see what you guys would do.

    This is on a 2020 2500 crew cab daily driver.

    I dropped it down to 58 front, and 60 rear as well as chalked them.

    I'll see how that rides in the morn.

    The last truck i ran 42 x4 and got 35k out of the same brand tires.

    This is the 3rd set of this brand I've owned and the first set I sold with 35kish on them, and the other person ran them for well over 5k more.

    However, my last truck was a 1500 ram, but they were the same tire, ply and load rating same rim width and diameter, just different lug count.

    If the psi doesn't fix the problem, I'm going to bushings and steering components to weed out the cheapest first.

    I'm having a little problem that I'm not sure how to resolve.

    My tire pressure light in the dash won't go out unless I'm running 80 PSI in the rears and at least 65 PSI upfront.

    Sorry if this has been addressed elsewhere, but this post grabbed my attention while having my eggs and juice this morning.

    Are you running an MM3?

    If so, you can change the values in the menu on tire pressures.

    Also, could it be maybe your tire sensors need to be replaced?

    I'm on OEM wheels (20 x 8) with 285/65/20 Cooper AT3 XLT's (34.6" or a 35" spec)

    I'm running 65F and 50R empty - I could probably drop the rear to 45, but it rides excellent - the front end is heavy I wouldn't drop the psi too much.

    Note that I was running 55F and 45R on the stock Firestones, and even though I increased the psi, the Coopers ride AMAZING to the stock junk Firestones.

    I had 57 this morn cold on all 4 and, after a couple of miles down the road, heated up to 60 across the board.

    If you go by the chalk line theory, it was gone, so the ride was soft and felt similar to my old setup.

    I might adjust the front top 60 cold, and I do think my problem is elsewhere tho.

    It still wanders in the road, and the steering wheel slop is still there, and I didn't think it would fix it completely.

    The factory drag bar is welded due to recall, and the wheels are straight around 11 o'clock on the steering wheel.

    I will attempt to cut the pigeon crap welds off between the nuts and adjuster sleeve to fix the steering wheel alignment.

    As far as steering slop and the wandering other than the steering box, what could cause the issue?

    My next step would be looking at a new track bar and stabilizer before i spend 700ish for the box.

    Empty I run 60-65 in the front and 42-45 in the rear.

    When I'm towing, I bump the rear up to 65.

    The tires are 35" Nitto Ridge Grapplers.

    I run 65 F / 54 R unloaded on my 35s.
