Most vehicles today are equipped with a Tire-Pressure-Monitoring System or TPMS. The TPMS is an electronic system used to monitor the air pressure inside your tires and alert you if they become under-inflated. If your “low pressure” warning light comes on it means your tire pressure has dropped 23.25em or more below the manufacturer’s recommended level and you should bring your vehicle in for service.We recommend you have your tire pressure checked every time your vehicle is in for service and your TPMS checked every time you have your tires rotated or balanced. A malfunctioning TPMS will fail to alert you if your tire pressure is too low and can contribute to increased braking distances, poor handling, and early tire replacement.Properly inflated tires lead to increased fuel savings and extended tire life. However, under inflated tires are the #1 cause of tire failure and a faulty TPMS may lead to vehicle handling issues if you aren't informed of this problem. From an environmental point of view, correct tire pressure and properly functioning sensors will help reduce CO2 emissions and keep your tires from ending up in a landfill prematurely.
