Tire Pressure Monitoring System is a wireless RF sensing device designed to measure the tire pressure and temperature, and LC-D can display tire pressure data. Once installed in your vehicle, the system will automatically monitor tires in rear-time for pressure and temperature. When any tire's pressure or temperature appear abnormal, the system wil, in rear-time, transmit signals to activate an alarm to warn the driver of tire problem. TPMS can help you to avoid tire accidents due to tire failure, to reduce the fule consumption and to extend the tire life.
