How the tyre pressure monitoring system works | TPMS |

What are the advantages of the TPMS? What is the difference between active and passive TPMS? Why do we need it? This video shows. 00:00 Tyre pressure monitoring system (TPMS) function 00:28 Active TPMS 01:04 Passive TPMS The tyre pressure monitoring system (TPMS) ensures that the tyres maintain the correct tyre pressure. In the event of loss of pressure, the driver is alerted via the TPMS warning lamp. All newly registered passenger cars have been fitted with TPMS ex works since 01/11/2014 at the latest. A distinction is made between passive (“indirect”) and active (“direct”) TPMS. WHAT ARE THE ADVANTAGES OF A TPMS? • Up to 40% of all road accidents are associated with insufficient tyre pressure. • A reduced tyre pressure of around 0.4 bar below the set-point value results in increased abrasion on the tyres. Less abrasion increases the durability of the tyres. • The higher rolling resistance with insufficient tyre pressure ensures increased fuel consumption of up to 0.3 l per 100 km, which in turn increases CO2 emissions.
