All,

Just wondering what the ideal air pressure is for my jeep/tire combo.

Typically, the trails i run don't require me to air down, but after a run yesterday, it was apparent that I had to. When airing back up, i quickly realize i don't know what the optimal air pressure for my setup when getting back on the pavement. I went off the standard recommendation of 35 in the rear and 30 in the front, but from what i can see, dust vs. no dust on the tires, i might be a bit under-inflated

My jeep is the 2 door sahara, with 33 Mickey Thompson MTZ's. No aftermarket bumpers or anything to add weight.

Suggestions are appreciated!

Do the chalk test.....

draw a thick chalk line across your tire and drive it a few feet. Get out and see how the chalk is wearing, if wearing on the outside use more pressure, if wearing on the middle use less pressure. Once the chalk wears even you are good to go....

My guess is you will be in the 30-32psi range.

 

X1 on the chalk test im running 28psi and im loving it

 

Do the chalk test. Just a side note, I usually run 30-32 up front and 28-30 in the back depending on the season and if I am towing.

 

Chalk test has me running 29-30 psi

 

27-28 in my 35's

 

I run 30 psi in my 34x10.50 Super Swampers! I'm gonna do the chalk test though!

 

I'm 28 in my 35's too. When I'm loaded for camping I bump the front to 29 and the backs to 30. Offroad 12 works real good.
