How the TPMS for 4x4 vehicle works

Each tyre valve stem has a sensor capable of measuring tyre pressure and temperature in real time. The sensors send data through to the dashboard receiver and display the tyre pressures and temperature on the screen. Info is updated every 4 seconds.

The tyre pressure baseline is set by the user.

The sensors:

Sensors are mounted internally, monitoring both Tyre pressure and temperature.

The Dashboard display:

The display screen visualizes The temperature and pressure in real time.

The quality of your tyres, and the tyre pressure are integral to your vehicle’s performance, fuel efficiency and your safety while driving. Tyreco Pressure Monitoring Systems monitor the pressure and temperature of your tyres, allowing you to make your wheels go the distance and last longer.

The Valor range of internal TPMS’s has been devised primarily as a safety device with the added benefits of being able to monitor your tyre pressure every time your 4×4 is being used, thereby avoiding under inflation and the associated tyre wear, higher fuel consumption and the hassle of having to check your tyre pressure at every filling station.

Each tyre is fitted with an internal sensor unit that monitors the real-time tyre pressure and temperature in each wheel. When driving the sensor sends a signal to the dashboard display every four seconds. In the event of sudden air loss, the alarm will sound and the display on the dashboard will indicate which tyre has a problem condition.

The internal sensors also warn the driver about other aspects like high pressure, high temperature, low pressure and slow air leaks – an added bonus for all 4×4 users.

This internal TPMS will give every driver peace of mind, will improve your vehicle safety and fuel economy, will enhance your vehicle’s performance and extend the life of your tyres.


There are 2 parts to the fitment of the TPMS namely:

  1. The 4 internal sensors – Fitment centers are trained to fit these type of tyre pressure monitoring sensors that replace the 4 standard valve stems and are similar to the sensors found on the BMW’s, Mini’s and Merc’s these days. The sensor fitment and wheel balancing takes about 1 hour for 4 wheels.
  2. The Dashboard display unit is supplied with a cigarette lighter power input as well as a permanent 12 volt connection, 12V permanent connection is recommended as this will indicate a detected ‘overnight’ flat tyre before the vehicle is driven the following morning.

Tyre temperature and pressure alarms on the 4 wheel road (201 D) TPMS are not fixed as the base tyre pressure can be set by the user.

The Tyreco TPMS unit is designed to give you:

  • A low tyre pressure warning
  • A high tyre pressure warning
  • High tyre temperature warning
  • Rapid air leakage warning
  • Slow air leakage warning
