What PSI for 35" Trail Grapplers on a 1500?

[Phylodog]

Just curious what you guys with 35" Nitto Trail Grapplers on 1500's are running for air pressure? Mine were shipped with 40psi in them. Hoping someone who's had them for awhile will chime in and shed some light on what would be appropriate. My Jeep had cupped MTZ's on it when I bought it and I do not want that to happen with my new tires.

I always run about 38-40 psi

I've got 33s.
The guy from the wheel shop filled them to about 40 psi.

should state the recommended PSI on the tire......thats your answer.

The number that's on the tire is the max air pressure recommended. With 35's I'd run 38-42 psi. I'm going to run 40 when I get mine

I ran 50psi on my 35s and Im now running 35psi in my 37s. Depends on how you want them to wear and how you want them to ride.

Grab some tire chalk and run lines across the tread, drive around and see how they wear.

Start at 40psi and go from there

Has anyone taken these tires through deep snow?

I would do the chalk test to see exactly where your pressure should be

whatever you do, dont do this.


i would start at 40psi. increase/decrease the tire pressure in 2 psi intervals until you find that sweet spot. keep in mind, the amount of pressure in the tire makes no difference on the size, so technically you should follow whats on the door. however, you most likely went from a d rated tire to an e rated tire and the e rated tire will ride better with a little higher pressure.
