and that's the reason i don't buy used tires.

 

I might be wrong but I think if it says 50psi it means 50psi at max load.

 

i run my tires at what they say they ride well as of now and i REALLY want new tires something with some **** and for one caged i didnt buy used tires bought them with the jeep and they were about 6 months old the guys that had this jeep before me were total idiot from Cedar Lake In guys name was Tyler . but i under stand what you guys are saying about max load and everything but i like the way it rides as of right now. i am really going for BFG'S KMO2'S 32x11.5x15.

 

when you get your new 32's, don't run them any higher than 28psi on the road.
you can air them down to about 15 on the trail without worrying about bustin a bead.

my previous post was only stating that most people over inflate their tires, which in time destroys the belts making them crown and wander all over the road.

 

Just because your tire is rated at 50 psi does not mean you need to run that high. that same tire can and does fit more thatn an xj. so the weight of your rig should dictate how much air you run. If you look in the door for the manufacturer placard it will give an good start of what is recommended and even if you have put larger tires on it will still work ok for you.

 

x2 On the over inflating!
Load range D & E range tires are basically for use on heavy trucks that haul heavy loads. When they have a MAX load rating of x number of pounds at 50 psi, that is for something like a one ton pick up, maybe hauling a cord of wood and pulling a loaded trailer, not for a 4000 lb or less Cherokee.
I'm running 35x12.50 r15s at 22 lbs on the road, and tire wear and gas mileage are good.

 

45lbs its crazy. I have 40s and run them at 22lbs

 

i ran my bias 36 iroks at 12 on the road.

 

Yeah I had them at 25. didn't seem to make much difference

 

Ok this is a sweet thread, actually answered quite a few questions I had.
So I run my 31-15's at about 28 on the road in my dd/rig and it drives true. 30+ and it gets bouncy and bump steers bad
Usually 20 on the trail.
On my tow rig, 40 in the front on d rated michelins for traction/steering and 35 rear on my BFG's
Perfect!
I'm not a "noob" with full size vehicles, but with the XJ I am
Big difference!
And I'll never go back! Unless I gotta haul wood...
