The Tire Pressure Monitoring System (TPMS) is an electronic system designed to monitor air pressure in tires. TPMS offers a wide range of benefits for drivers:
- Improved fuel saving of up to 10%
- Improved road performance and traction
- Decreased tyre wear
- Reduced CO2 emissions
Since November 1st, 2014, all passenger cars in the EU must have a functioning tire pressure monitoring system (TPMS). Just as the rubber valve has been renewed in the tyre service so far, individual components of the TPMS sensor must be replaced by new ones. Whenever a tyre is replaced, the suitable TPMS Service Kit must be used to replace the wear parts (nut, O-ring, nickel plated valve core, cap). This ensures safety, prevents breakdowns and avoids larger and more expensive consequential damages (e.g. a complete replacement of the sensor due to the nut and the valve core are stucked by corrosion).
Causes for malfunctions
- Corrosion of metal components
- Embrittlement of rubber seals
Possible consequences of malfunctions
- Creeping pressure loss of the tire due to leakage
- Seizing of the metal parts on valve and rim, which requires replacement of the complete sensor
- Sudden failure of the valve core, e.g. when filling the tire
ACCORDING TO THE AUTOMOBILE MANUFACTURES‘ SPECIFICATIONS, TPMS-SERVICE KITS MUST BEREPLACES ON EVERY TYRE CHANGE – FOR YOUR OWN SAFETY!
