If you call to order you can request they pre-set them to whatever tire pressure you want. I asked for 10, and I got 10.
Some days I'm at 5 or 6 psi on sand, 8 to 10 for rocks and trails, 15 or lower depending on washboards for long days on forest service and rural gravel roads, and whatever it takes in deep snow. No preset auto deflator is going to do the job. A Currie style deflator and, for accurately setting very low pressures an Accu-Gage low pressure tire gauge (with the stem painted bright red to avoid a mistake), is fast enough and fits the bill for that kind of use.
don't forget to ask what tires / load range and how much his rig weighs to make that info matter somewhat
That isn't the point and I think you know it. The point is there are plenty of new Jeepers coming through here and they need to know that a particular gizmo isn't necessarily the answer for what they might do just because some cool kids like it.don't forget to ask what tires / load range and how much his rig weighs to make that info matter somewhat
Actually it IS the point, that new wheelers shouldn't be directed to a specific PSI (or even a set of them based on terrain) based on tire size alone, this is poor teaching. Proper teaching explains how to determine a good PSI for their rig, which depends on more than just tire size and location. He didn't ask about or comment about the gizmo in question.
Both of y'all are right. I've got deflators and a compressor setup already and know the right pressures for my rig. I was simply just curious what pressure others were running their tires. And I needed to the reminder about the difference the specific tire and rig make.

Anybody run different pressures F/R? I have 35/12.5/15 and run a little higher in the front thinking that the weight will squish it more?
25/22 around town/highway but running 14/12 on AZ rocky trails - no issues yet, Maybe I'll go lower after reading this thread - could always use a smoother ride!

do you know how much weight is on the front / rear axles? If not, why assume? I don't run them any different front to rear, but I also have weighed my rig fully loaded and know the weight ratio is darn near 50/50 front to rear.

Weight bias would have to be way off to warrant running different pressures... eg. Diesel truck with no weight in the bed...
You're overthinking it. I just pick one PSI and do all 4 tires.
I would also think 14 and 12 are a bit high for a TJ. Try 10 or 9. If you don't lose a bead, then you're fine.

Quite true. And it wouldn't bother me to burp really bad or lose a bead as long as I don't roll out of the tire. Not sure how to mount it out on the trail?
Here's a cheap kit that would be perfect trail use. It wouldn't be a bad idea to watch some videos or eve go down to your local tire store when they're not busy and see if they would be willing to give you a hands on demonstration... It's a lot easier than most people think.

Getting the tire on might be the easy part.
Straightening a rim, fixing a large gash, or cleaning out a bunch of mud is the bitch.
Just carry a spare.
I've heard you can going lower in the rear for sand/snow as the front is more likely to lose a bead while turning. I don't have enough experience pushing things that hard, but it sounded plausible enough.

Curious, what would be your suggestion for me on these tires and fairly lightweight build?
Give one for service road and one for hard off-road, rock and ruts.
(This is correct size tires as well)
