Features 1Tyre pressure that is too high or too low will cause tire wear. TPMS helps reduce tire wear prevent tire explosions save fuel and maintain good car maintenance. 2With the help of TPMS we can keep the tire pressure and temperature within the specified range at any time to reduce tire damage and ensure driving safety. 3Solar charging + USB charging no need to connect the car cigarette lighter to charge high power transmission and high performance wireless connection with the sensor easy to install. 4The color LCD digital display can clearly display the tire information during the day and night and monitor the pressure and temperature of the 4 tires in real time. 5Low air pressure/high temperature alarm; high temperature/leak/low battery alarm; smart shockproof cover when the car is driving no need to open/close. 6Over 40% of traffic accidents on highways are caused by abnormal tire pressures. In order to reduce such accidents a tire pressure monitoring system (TPMS) must be installed.
