TPMS monitors tire temperature and pressure in real-time. 83% of tire pressure loss is estimated to occur gradually – often without being noticed by the driver. Correct tire pressure helps reduce fuel consumption, and reduces tire wear, the risk of aquaplaning and lack of traction. New 4 Internal Sensors TPMS Tire Pressure System Displayed on Car Monitor.
