Frequently asked questions

WHAT DOES THE TERM TPMS MEAN?

The term “tyre pressure monitoring system” (TPMS) is defined by the directive (EC) No. 661/2009 as follows: “Tyre pressure monitoring system” is a system that is mounted on a vehicle and which evaluates the tyre pressure or fluctuations in pressure over time and can supply appropriate information to the user during travel [Reg. 661, 2009].

Central Tyre Inflation System (CTIS) is a system which offers air pressure control in every tyre of a vehicle to improve the performance on different surfaces, e.g. By reducing or increasing the air pressure. CTIS are not included in this inspection because they do not come under the definition of TPMS. No “external” tyre pressure monitoring systems which monitor the tyre pressure on the basis of a tyre pressure range measurement are included either.

WHAT REGULATIONS CURRENLY EXIST FOR VEHICLES (CLASS M1) AND LIGHT COMMERCIAL VEHICLES (LCV)?

In order to reduce emission in road traffic, the European Commission has implemented a strategy for light commercial vehicles (LCV) with the aim of limiting the average CO2 emissions. The directive (EC) No. 443/2009 and the directive (EU) No. 510/2011 contain binding CO2emission standards for new private vehicles and light commercial vehicles.

IS A TPMS COMPULSORY FOR LCVs AND HCVs?

There is no regulation on TPMS so far. Whereas, for vehicles of class M1, TPMS were prescribed in 2012 for new vehicle types and from 2014 for all vehicles (directive (EC) No. 661/2009), no such binding requirements apply for LCVs and HCVs even if a TPMS could contribute towards a reduction of the LCV and HCV fuel consumption and CO2 emissions.

WHAT ADVANTAGES DOES THE TPMS HAVE FOR OUR ENVIRONMENT?

Under-inflated tyres have a higher rolling resistance than tyres that are used with the specified tyre pressure. This leads to an increase in the fuel consumption which means that more CO2 and other pollutants are emitted. By using a TPMS, tyres with fluctuating inflation pressure can be prevented and therefore bring ecological benefits due to lower emissions.

The CO2 emissions of heavy commercial vehicles (HCVs) which account for about a quarter of the CO2 emissions in road traffic are not regulated at the moment. As a result of the continuing increase in freight volume in the EU (except for in 2009 due to the economic crisis), these emissions have increased despite some improvements in the fuel consumption and CO2 emission of the vehicles. In June 2007, the Council demanded that the Commission “develop and implement political instruments and measures to reduce the greenhouse gas emissions of these vehicles.” In their bulletin “A European Strategy for Clean and Energy-efficient Vehicles” of April 2018, the Commission announced that they would suggest a strategy for the fuel consumption and CO2 emissions of heavy commercial vehicles.

WHAT SAFETY ADVANTAGES DOES THE TPMS HAVE FOR THE TRUCK DRIVER?

The dynamic behaviour of a tyre (e.g. braking distance and lateral stability) is closely related to the set inflation pressure. Under-inflation can lead to reduced vehicle stability in situations critical to safety (e.g. Fast steering response, driving through bends, braking in bends) which increases the risk of accident. An extreme inflation pressure deviation can lead to thermal and mechanical overloading and subsequent, sudden destruction of the tyre itself. The use of TPMS can prevent tyre pressure deviations and therefore has a safety advantage thanks to maintaining the vehicle stability.

 

Welche wirtschaftlWHAT ECONOMIC ADVANTAGES CAN BE ACHIEVED BY USING THE TPM SYSTEM?

The TYLOGIC® TPM system can lead to a reduction in running costs and corporate costs for several reasons:

  • by improved rolling resistance
  • reduced maintenance costs
  • longer life of the tyres
  • optimised inspection intervals
  • fewer tyre failures
  • reduced breakdown costs
  • reduction in the external costs
  • reduced number of accidents (deaths, injuries and traffic jams)
  • reduced volume of emissions
HOW LONG DO THE SENSOR LAST?

The life of the sensors in the TYLOGIC® system depends on the life of the battery of the TPMS sensor (between 3 and 10 years).
