I ran 32 psi in mine. I always have run 32 on every vehicle I've owned. None of them had larger then stock tires though. I do run the 35's I have now at 30 though.

26 psi for my 33" Duratracs, 22 psi when I had 35" Cooper STTs.

To get the best wear and performance out of your tires, you'll want to do a chalk test. That way you get the best wear, and ride possible.

Drive to a flat area. This can be your driveway or the street in front of your house. Just make sure there aren't a lot of cracks, bumps or pot holes in the ground. Draw a thick, straight line across the width of the tire. Drive the car forward at least one-full car length.Inspect the chalk on the ground and on the tire. A tire with the proper air pressure should press the chalk line evenly across the ground. This means you'll see the entire chalk line imprinted on the ground. An over-inflated tire will bulge and only the center of the line will touch the ground. You'll only see a small portion of line if this is the case. If you're tire is underinflated, you'll see only the sides of the lines since the middle of the tire is not making contact with the ground.
Adjust your tire's air pressure according to the chalk test results.



Hope this helps!

Actually tire pressure should be between 28 psi to 30 psi and its a ideal tire pressure. you can increase or decrease as per road condition.

I'm running Wild Country MTX'S AT 30 psi now but I'm going to drop them a couple pounds. Rough ride and all the tire not making contact with road.
