After watching Teraflex's video, I told my wife and her Dad that we should be airing down to 15 psi everytime we hit the trails, even if just for comfort. They both thought that was too low. I feel like Teraflex knows what they are talking about, but I also trust my father-in-law. Afterall, he has taught me more about off-roading than anyone else. So that begs the question, what do YOU air down to?

I go down 18 psi from 32 psi. They may be afraid that, that low will pop the bread off. Next time you with them air down to 15 psi and see how they like it.

When I had my stock tires I found that going down below 18 was damaging my rims. So I would drop to 18. Now with 37s I drop it to 15, although I am still experimenting with the new 37s on stock rims. I might drop to 13 this weekend.

I always air down to 12 psi and I do not have bead locks. I have scratched my rims a little but have never popped a bead.

I do not run beadlocks yet. When I ran 35's I took it down to 13 and got great performance out of them and never popped a bead. I now run 37's and like to run a little higher with those. 15psi seems to do just fine. Running too low psi can/will pop a bead and has the potential to damage your wheel.

Depends on a number of factors; 2dr/4dr, size of tire, load range of tires C, D or E, 2ply or 3ply sidewalls, MT or AT, gross weight with mods + cargo and terrain.

Stock Jeeps aside, no two Jeeps are really the same. What works well for one might not work as well for another. All that said, I found that 17-18 psi on my 34" KM2s with 3ply sidewalks in load range E works the best for my JKU, which I run on the heavy side with armor and cargo.

If you are not sure start at 20psi and work down. It is less hassle to take out air than put it back in. Especially if you do not have a portable air system of some kind with you.

I run 15lbs on 35" Open Country MTs. Side walls are load range E so they barely flex... lol

Newbie here, aired down I assume that the TPMS will be sounding off like crazy. is there a temp disable when airing down? Thanks in advance

The warning light stays on, but it only beeps when you start. With only the dash light, and no constant beeping, it doesn't bother me. You lower the PSI level that triggers the warning w/ a programer.
