What is Winter TPMS?

A Tyre Pressure Monitoring System or TPMS is an electronic system for monitoring the air pressure in a vehicle tyre and automatically transmitting a warning to the driver in the event of an under or over inflated tyre.

The majority of systems use direct tyre sensors which transmit real time tyre pressure information to the driver of the vehicle either via a dashboard display or a warning light. The sensors are physical pressure transducers which are attached to the back of the valve stem. The sensors are manufactured by International companies such as Schrader, Siemens, TRW, Pacific, Lear and others. There is no common technical standard for the sensors and the OE's and suppliers have generated a multitude of sensor designs.

The sensors also transmit data such as their unique sensor ID, temperature and pressure, battery life and other diagnostic information. This data is sent to the Engine Control Unit (ECU) or specific receiver on the vehicle. Those vehicles which have graphical displays of the TPMS positions can then show on which wheel there is a problem
