Features: Tire pressure monitoring systems are used to increase the length of driving, reduce for extra oil reduction from insufficient tire pressure and extend the working life of tires. Used in the car running, can real-time for tire tire pressure is too low, tire pressure is too high, fast leakage, tire temperature is too high and battery voltage is too low information for automatic monitoring and alarm, to provide the driver with effective information to maintain enough tire tire pressure, prevent the occurrence of tire burst accident. Excessive or low tire pressure during driving, for any reason (such as foreign body piercing the tire, tire scratch...) If the tire leaks, the system will automatically alarm immediately, so as to ensure safe driving. TPMS wireless tire pressure monitor uses the world's top line induction chipset, has a number of wireless communication patents, no need to install a repeater. When the car is running at high speed, the signal is received accurately and can reflect the tire pressure most directly. It is the most stable tire pressure system with current technical performance.
