OUr Story


 The idea for J.T. Brooks Automatic Tire Deflators started back in 1983, when two friends, Jon and Brian, ventured up to Lake Champlain in Vermont to meet up with family and friends for a weekend of ice fishing. On the long journey from Boston, MA, Jon mentioned that he needed an idea for his manufacturing engineering senior design project. Almost immediately, Brian mentioned the idea of a mechanism to automatically deflate your tires to a set PSI. Brian, who was from Cape Cod, would go to the beaches regularly and deflate his tires to improve his vehicle’s traction on the sand. He felt that the current deflation process of using a tire gauge and sharp object was long and tedious. Each tire had to be deflated individually and the tire pressure would have to be checked with the tire gauge over and over until the recommended PSI was reached. If you deflated your tire too far, it was a hassle to air it back up, only to deflate it again. They thought, “There must be a better way to do this!” After a year of research and tests, J.T. Brooks Automatic Tire Deflators was launched in 1984.   


J.T. Brooks focuses on making a high quality product that conveniently and accurately meets the customer’s off-roading needs. We have expanded our product offerings to better meet everyone's off-roading needs. Our keychain tire deflators allow users to measure the instantaneous PSI in his/her tire by placing a tire gauge over the threaded end, while the tire is deflating. Our automatic tire deflators, which have been available since 1984, can be calibrated to a desired PSI. This allows the user to simply screw them on and attend to other tasks before off-roading, as the automatic tire deflators quickly and accurately deflate each tire, while stopping deflation at the calibrated PSI. Our automatic tire deflators pro elminates the need to calibrate each automatic tire deflator. Simply dial in your desired PSI, using our precision laser engraved PSI scale, and go!* The automatic tire deflators pro allow for easy change in desired PSI, while on the move.
