I was wondering about tire pressure for 35s to get a even wear on them ... Right now I'm running 40psi should I be running lower or higher ???

 

What size wheel/ width are you running and what kind of tire? In general, 30 psi is a good number, but ideal for your particular set up could be +/- 5 psi.

 

Depends on the weight of your rig including all the add-ons, but usually, 30psi is about right. That's what I run on my 37's and it wears great across the tread pattern.

 

There are many factors in determining this. Vehicle weight, wheel width and tire load rating are the main ones, and doing a chalk test is the best way to find out the exact amount of pressure you should be using for your setup. As mentioned, 30 psi is a great starting point.

 

I agree. I have a heavy rig and the tire rating says 50lbs cold pressure. I did the chalk test and run with 30lbs...tires run even wear.
