When to Air Down/Up Mountain Trails

geiman · Sep 10, 2012

Like I said previously, the 20lb tank is indeed very large, and almost too big for a wrangler. But, if you already have a 20lb tank it's definitely doable. Once I got the mounting situation figured out, it kind of all fit in place. Initially I wasn't sure I would be able to find room, but now I'm kind of glad I stuck it out. The 20lb tanks fits neatly in the back just inside the tailgate on the passenger side quite well. It works great for me; I try to carry as little as possible off-road, so space for me isn't really a big issue. A 10lb tank is possibly slightly easier to store in the Jeep, but in my opinion it still takes up close to the same amount of real estate. If you mount them standing up, the difference in space used isn't that much. A friend has a 10lb tank and the space wasted is about the same.

That said, either tank would work well for airing up tires; size is pretty much personal opinion. They all get the job done.

As for capacity, I haven't had the tank long enough to empty it. I've used it on at least 5 or 6 trips so far, each time airing up 4 33s from ~10 to 25 PSI. Powertank has a chart here that has some estimated usage figures:

I air down to 18psi at the trail head...do yourself a favor and spend $80 and get the Staun Tire Deflators....you get a set of 4 and they screw right on to your valve stems....they automatically cut off at 18psi....you can adjust them to a different setting or buy ones set at a lower default psi setting.....you can air down all 4 tires at once, don't have to stand over each tire with a pressure gauge and check each one constantly.....they are awesome.....then take them off the valve stems, put the caps back on and start wheelin'!!! Then air back up as your leaving the trails....

I have the Staun deflators, and while they're nice I hate waiting on them. I picked up one of Currie's EZ-Deflators and I can be done about 4 times faster then if I use the Stauns. It actually removes the valve stem so things go a lot quicker.

A big X2 on Geiman's recommendation for Currie's EZ-Deflator. I can be done airing down all four of my 35" tires from 24 to 8 psi using my Currie deflator much faster than someone else can be done airing down just one tire using other methods that don't remove the valve stem like Currie's does.

ARB sells the same deflator with their name on it.
