Oasis Off-Road’s Trailhead Automatic Tire Deflators

Finally! For such a simple and awesome product, it sure took me a long time to getting around to doing this review… Anyway…

When I had my 31’s, airing down by hand (i.e.: squatting by each tire with a letting air out with a tire gauge letting) didn’t take all that long, but once I got my 33’s it seemed like airing down took forever! Most of the rigs I usually trail with run 31’s so they were all aired down, disconnected, and ready to hit the trails before I was done with my tires, so something had to change. I’d been eyeing the Trailhead automatic tire deflators from Oasis OffRoad for quite a while, and decided it was finally time to try out a set.

What really sold me on the Oasis deflators is that unlike any other deflating device, they automatically shut off at a pressure you set, so you can screw them on and do other things (like disconnect your swaybar), then just pull them off when they’re done and you’re ready to go in less than a 1/4 of the time it used to take you to air down (the deflators are slightly quicker than letting the pressure out by hand, and you can deflate all 4 tires at the same time).

At $56 a set, plus shipping (mine worked out to $62 total), they’re not exactly cheap, but they’re well worth the cost if you’ve got big tires and air down to run trails (which you should do anyway). The kit comes with a tan leather carrying pouch that fits perfectly in the glove box, 4 anodized aluminum delfators (in your choice of red, blue, or polished aluminum), a matching low-pressure tire gauge, an allen wrench for adjusting the deflators, a laminated instruction card, a deflation guide, and of course a window sticker.

The deflators themselves are about 2″ long and you can get them in two different pressure ranges: 8-20psi or 20-40psi to fit the pressures you like to run. Since I usually run my MT’s at 12-15psi on the trail, I chose the lower pressure rating. The matching tire gauge is setup for the pressure range you select, which is nice considering most tire gauges don’t read low pressures very accurately. Setting the shutoff pressure is easy, all you do is use the Allen wrench that comes with the kit to turn the adjusting screw in the deflator. Every complete turn equals about a 1-2psi change — turning the screw clockwise increases the pressure, counterclockwise decreases it. The first time I used the deflators my tires were all within 1psi of eachother, not bad I think.

Oasis Off-Road also sells the QuickAir line of air compressors, PowerTanks, and the Outback dual battery welding system.
