We came across J.T. Brooks at an event held in Norwood, Ma back in July 2015. They specialize in tire deflators and we were very interested. We got a pack of their Pro Series Tire Deflators soon after and were not let down! We take our Jeeps to the beach and to the trails quite often, so airing down is a common occurrence with us. Along with airing down before hitting the trail, some vehicles require the sway bars to be disconnected, the GPS Maps to be calculated or just double checked for tools and requirements prior to hitting the trails or the sand. Why waste time checking each individual tire when you could use tire deflators to do the work for you? These easy to use tire deflators simply screw onto your tire valves and do their job! They're adjustable from 3-32 PSI and all you need to do is dial in your desired tire pressure and screw them in! This gives us time to prepare other things for our trips, rather than crouching down next to each tire and constantly checking the pressure. The best thing about these deflators?? They are quick and extremely accurate! Once you're down airing down, simply unscrew the deflators and pop your valve caps back on. Easy as that! They come in a small storage pouch so they're always kept together in a safe spot! Money well spent! Next time you're airing down and taking up valuable time checking each tire when you could be getting other things done, remember J.T. Brooks and order yours today!
