Have about 20,000 miles on them so far and about 10 full days of wheeling on them as well. This is my dd and my trail runner, I run 28 pounds of air in them on the road and depending on the kind of trail I am running I don't even bother to air down, they have that kind of traction. If I am doing stuff where I need more flex or a bigger footprint then I let them down to about 15 with great results.

Just shy of 45,000 on my ProComp MTs and nothing is broken. They are out of round and won't balance worth a shit but they still roll. I need to look into new tires soon.

I found a HUGE difference between 32 and 37 psi on my KM2's. Found 32 to be about right for DD and 37 for long trips to conserve fuel. However, I Will wear the middle of the tire first if I run it too long that high IMO.

I run 40psi in my KM2's. So far I have about 35k miles on them and still have just under half the tread left.

I drop that to 15psi when wheelin.

35,000 miles on my 35 " Toyos. Nothing broken but the E rated tire is plenty stiff for a 2 door. They have been wheeled on everything frrom the Rubicon trail to Moab skickrock. I run around 26 lbs for the road.

Why the big difference in the psi you guys are running? One guy 40, another 26? That's a big difference. Why?

40 if you like riding on bricks. I find anything over 35psi to give you one of the harshest rides imaginable and it causes the tire to wear unevenly in some circumstances. True test is to do the chalk test and narrow it down to what works for your Jeep and it's set up. I normally run 33psi in my 35's and they have been wearing evenly for over 10K now. It takes a little trial and error to get it just right but whenever I take it to the dealer they fill them up to 40 cause it's what they say and as soon as I start to drive home I can feel every bump on the road and have to pull over and let some air our.
