Tire Pressure

[Chris99XJ]

I have Pro Comp 32" x 11.50" Tires,  They say 50 psi MAX @ cold temp
When i checked the aire pressure in them the other day,  They all were @ 38 to 40 #'s.

What should i run them @ beeing my daily driver ?

I'm not retyping what I just put on MJ. :twisted:

Isn't 35 considered the red standard for daily driver tire pressure?

adjust them until your tread sits flat on the ground. i ussualy drive over water, salt or dirt, to see if its too high or low, then adjust as needed

best bet is to do the old chalk test ... draw a line on the tire drive it a few hundred feet on flat ground and see where the lines wears off. If its gone on the outside of the tire then theres too much pressure, if its missing in the middle then theres not enough ! I'm only running 26 pounds in my Goodyear MTR's 33-12.5-15

A good starting point is the "official" reccommended Jeep pressure printed on the tag inside your door opening or on the end of your door.  That should get you close, then use the chalk method as Tony described.  Running 12.50" tires on 8" rims, I don't get a flat contact patch until down around 25 front and 23 rear.
