Reviews for Quadratec RES-Q Automatic Tire Deflators w/ Carrying Case

Great

Price, You can set the desired PSI and even the case.

These are super simple and convenient tools for airing down your tires! I used to use a rapid air-down tool where you screw it on, undo the valve core, and then let air out before doing those steps in reverse and moving on to the next tire. That was fine, but these are so much more convenient especially if you're like me and have to manually disconnect and secure your sway bar links before hitting the trails. So now I screw these on and let all 4 tires air-down at the same time while I finish prepping everything else.

Calibrating was super easy and only a matter of setting a tire to the desired pressure and then adjusting these. It's incredibly straightforward and the instructions tell you exactly what to do. Highly recommend these!

Pre-set deflation value

Saves time deflating tires when going onto beach.

This is the perfect little gadget for off-roading! I love that it comes with a little pouch!

Setting up was easy. Follow the instructions and they came within 1-2 psi from each other. From 35 to 20 psi on my 33-12.5 tires took about 6 minutes. If you're not in a hurry, they're great. Deflate your tires while you stand around with your buddies drinking morning coffee before the run.

Work well enough, not necessarily quicker than doing it yourself though.

The closer you get to your desired pressure the slower the air release becomes: ie. 40psi to 30psi may take a few minutes, then from 30psi to 25psi will take the same amount of time and so on).

They don't hold adjustment for more than a use or two and they're only precise to within three PSI or so. Great in theory but not as practical in practice. My advice is to buy a decent tire inflation gun with a gauge and just squeeze the trigger without an air hose hooked up. It works faster and is more precise.
