|mikes139||When I was running 33's I went around with about 20 to 25 psi in mine.|

|JFT80||It's amazing the difference in the ride once I got the PSI down to about 28. I no longer bounce like a basketball on the highway when I hit a bump. They had it up to 40+ PSI.|

|njkeagle||Isn't there also a way by calculating? Meaning you take the max load per tire and divideded by the weight of the vehicle? I know I figured this out before but not sure..Heeeeelp|

too many people see the side of the tire say max 44 psi, or whatever, and do that. wrong. tires fit many vehicles, you gotta go by what your application calls for.

The best method is to use the chalk trick. Rub a trip across your tire and drive around the block a couple times. If the center is worn, lower your tire psi. If the sides are worn raise it, and if its completely gone your good.
I believe the proper pressure for 33's is around 25 depending on your jeeps weight and such.
Judging by you saying the center of your tires are worn, I would suggest lowering it. I run my 35's at 22 psi.

Proper Tire PSI
Does anyone know the proper tire PSI on 33"x12.5"x15" Mickey Thompson tires? They seem to be more worn in the center.
