Accutire MS-4378GB Remote Tire Pressure Monitor System for Auto and Trailer for $79.99

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.
