Most vehicles today are equipped with a Tire Pressure Monitoring System (TPMS). The TPMS is an electronic system used to monitor the air pressure inside your tires and alert you if they become underinflated. If your “low pressure” warning light comes on, this means your tire pressure has dropped 25% or more below the manufacturer’s recommended level. We recommend you have your tire pressure checked every time your vehicle is in for service, as well as have your TPMS checked every time your tires are rotated or balanced. A malfunctioning TPMS will fail to alert you if your tire pressure is too low, and this 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, underinflated tires are the leading cause of tire failure. 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.
