TPMS system in trucks and trailers - responsibilities, technology and benefits

The Tire Pressure Monitoring System (TPMS) is playing an increasingly important role in heavy transport . Its task is to continuously monitor the pressure and temperature in the vehicle's tires, which translates directly into safety, driving economy and environmental protection.

Although TPMS has been mandatory in passenger cars for years, its implementation in trucks and trailers is also becoming a legal requirement. Based on Regulation (EU) 2019/2144, commonly known as the GSR2 Regulation (General Safety Regulation) from 6 July 2024, all newly approved trucks (categories N2, N3) and semi-trailers (O3, O4) must be equipped with a tire pressure monitoring system.

The aim of this obligation is to increase road safety, reduce fuel consumption and reduce CO₂ emissions by maintaining the correct tyre pressure.

How does TPMS work in heavy vehicles?

In commercial vehicles Diagnostic Tester TPMS Programmer
(A: 0882770) direct systems are most commonly used, with sensors placed in the tire valves or mounted on the rim. These sensors measure pressure and temperature in real time and transmit the data by radio to the control unit and then to the display in the driver's cabin.

In the case of semi-trailers and multi-axle sets, it is important to use dedicated multi-module solutions that can support a dozen or more wheels, often with the possibility of wireless synchronization between the tractor and the semi-trailer.

TPMS Service Tools

Professional TPMS service requires specialized diagnostic tools. For example:

• TPMS testers ( e.g. Texa, Hamaton ) – enable reading data from sensors, activation, programming and error diagnosis.
• Sets of programmers and replacement sensors – allow for quick restoration of the system in the event of a failure or tire replacement.
• Diagnostic interfaces ( e.g. Jaltest ) – offer integration of TPMS diagnostics with other vehicle systems, which facilitates comprehensive service.

Benefits of TPMS implementation

The TPMS system is not only a legal requirement , but also brings real benefits to transport companies:

• Increased safety – early detection of pressure drops prevents breakdowns, tire fires or loss of vehicle control.
• Fuel economy – Tires with lower pressure increase rolling resistance, which translates into higher fuel consumption. TPMS allows for ongoing correction.
• Extending tire life – maintaining proper tire pressure reduces uneven tire wear and overheating.
• Less downtime – responding quickly to problems helps avoid expensive and time-consuming repairs en route.

TPMS in trucks and trailers is a step towards modern, safe and ecological transport . Currently, it is a legal requirement for new vehicles, but it is worth considering implementing such solutions in your older fleets today - with a view to savings, driver safety and care for the condition of the fleet. In combination with the appropriate diagnostic tools, the TPMS system becomes an irreplaceable element of modern logistics.
