TPMS aims to

       The Tire Pressure Monitoring System(TPMS) is an efficient and effective solution to many of the current automotive safety problems. TPMS will help prevent driving on deflated tires and reduce gas(fuel) consumption. The TYREDOG WTPMS (Wireless Tire Pressure Monitoring System)is a relatively new technology which has captured the focus of the industry because of its unique valve stem cap sensor design.

     The extremely lightweight, compact sensor has been specifically designed to simplify and reduce the installation time. Through wireless technology, tire pressure and temperature information is displayed on the User-Friendly Graphic Interface(LCD Monitor).

A simply smart approach to having TPMS system

     The TD4000B-X-02 can support to four tires and can easily installed within minutes and without any technical knowledge. The User-Friendly Graphic Interface enables the user (driver)to understand and maintain their automobile tires in a safe condition.


            LCD monitor

The LCD monitor displays the tyre's pressures and temperature.

 Light and compact

Extremely lightweight and compact with specially designed electronic sensors.

 Battery power status display

The LCD monitor will display a low battery warming when either the monitor unit or any of the tyre sensors has low battery power.

 Abnormal pressure warming

The LCD monitor will send an immediate warning if any tyre is monitored and exceeds the pressure parameters that you chose to set.

 Transmission status display

The sensors will automatically transmit pressure/temperature date to the LCD monitor when it is turned on.

 Accurate tyre pressure sensors

Electronic tyre pressure sensors are accurate to +/- 1 PSI.

3MIN-DIY DIY installation 

Simply screw the sensors onto the valve stems in the place of valve stem caps.

 Anti theft sensor mounting design

Each of the tyre pressure sensors is provided with a specially designed locknut. This secures it tightly onto the valve stem and prevents easy removal.

 RoHS compliance

All components are complied with environmental protection requirements.
