J.T.BROOKS™ Automatic Tire Deflator, 4 Pieces (J0052528) by Steinjager®. No one likes wasting time squatting down and running from tire to tire trying to set each tire to the correct PSI for maximum off-road traction. If you frequently air down for off-road adventures, then these tire deflators are exactly what you need. Once set to a desired PSI, they are ready to use time and time again. These tire deflators automatically and accurately deflate tires to a set PSI. Simply calibrate each automatic tire deflator, by following the included instruction card, and lock them in place with the lock nut, screw them onto each tire's valve stem, and let them do the work. The deflators automatically shut off when the set PSI is reached. This saves the user much time and frustration.
