Accutire’s remote tire pressure monitor system helps you keep an eye on your vehicle tires so you do not lose air over a period of time. It is a fact: tires can lose 1 to 3 PSI per month. This is because molecules of air, under pressure, weave their way from the inside of the tire, through the rubber, to the outside. A drop in tire pressure could cause the tire to become overloaded, leading to excessive heat build-up. If a trailer tire is under-inflated, even for a short period of time, the tire could suffer internal damage. This system offers the right tool to keep tabs on the tire pressure of your auto, truck or trailer. The individual caps are programmable to read the tire pressure and alerts with an audible signal if a tire has a fast leak. The digital display is easy to read.
