I am curious,...

If you aren't having any traction issues on the terrain,...

Do you "always" air down?

I have been letting out about 8-10 psi to the mid to high 20's, but haven't been having any traction issues. Should I go lower to protect my tires from sharp rocks, or risk popping my beads in the middle of nowhere? I ask this because of my greater concern for the decrease in clearance I would have at a lower psi.

The general idea of leaving them on, is that you can put them on the valves then drive while they are deflating. I'd not leave them on for a long period of time. They are a fairly precision valve assembly so, I'd think that keeping dirt and moisture out of the internals would be a good idea. There's usually plenty of time to air down without having to drive, so I try not to drive with mine installed.

I run 14 PSI on my 33's. Generally the larger the tire the lower pressure you are able to run.

Just to stir the pot, I really like running at about 21-22 on my KMT2 285's. I had some issues with my Trailheads in that temperature effected them way too much. I ended up with the ARB deflator and really like it.

My Stock Sahara did ok when I was at Uwharrie in the mud without airing down in a few areas I had no traction at all but after airing down to about 15psi it was suprisingly better and for airing up it only took me oh about 2-3 seconds. Yes I said seconds. Being an avid paintballer I had a 4000 psi Nitrogen tank that was full and had gotten an Idea from a tool that Lowes sells. Well mine isn't regulated like the tool but works just as good with careful judgement and reasoning. IF YOU DON'T KNOW HOW TO DO IT DON'T BE STUPID AND TRY IT..... I had a coupler that fit the remote on a tank and connected it to an air chuck. Hmmmm opened the valve slowly and counted to 3 and had to let about 10 psi out of the tire. If you want to try this I reccomend using a nonlocking one to avoid over inflating the tire and I STRESS AGAIN, IF YOU DON'T KNOW HOW TO DO IT DON'T BE STUPID AND TRY IT..... Be Careful... They make regulated ones in several mags for around a few hundred bucks. or the one in lowes for about 80 something here are some links to them...

Don't think anyone mentioned this yet -- if you're aired down, keep your speed below about 20 MPH. If you turn the wheel while going too fast, you can pop the tire off the rim and instantly lose all the air in the tire. Think "aired down = 4WD Low."

X2, I have one and it did well, just gets really hot.

X3 I have one powering my on board air.

By the way the tank does help on the first one after that the air compressor takes over.

That's a cool idea, maybe something to consider for those that air up a lot.

No! My buddy has this and he is always the last person to be aired down sine he can only do one tire at a time and I can do 4 at a time. Not to mention he HAD to read the directions to figure out how to use it!

So I wouldn't recommend this for those 2 reasons.
