TPMS technology for wheels and mounted wheels - from Interpneu

TPMS - Tyre Pressure Monitoring Systems

Technical background and solutions

Tyre pressure monitoring systems (TPMS) are systems that are integrated into vehicles and constantly monitor the tyre pressure. If there is a loss of pressure in one or more tyres then the driver is informed directly via a display or a warning light. A distinction is made between direct and indirect systems:

Indirect systems

In an indirect system the loss of air is determined by the ABS or transaction sensors that are built into the vehicle. When changing tyres, the alternative that is much simpler and cheaper is the indirect system, because it is not necessary to use TPMS sensors and you do not have to worry about anything being new when selling and installing mounted wheels. However, it can be the case that an indirect system needs to be recalibrated after a tyre change.

Direct systems

In a direct system the air pressure in the tyre is monitored by the sensor that is built into the wheel. This information is sent by radio to a controller in the vehicle. The information for the driver is shown on a display of the onboard computer. A direct system entails higher costs when changing tyres: The installation of the sensors is done with a special tool with a preset torque and special equipment units and programs are required to read the sensor data and teach-in the sensors, etc.

Types of sensor

OE sensors

These are the same as the sensors that are provided as original equipment. The software protocol of the corresponding vehicle has already been installed. We can offer you sensors from makers Schrader, Huf Beru and VDO. We can cover a large proportion of all relevant vehicles with these.

Universal sensors

This involves an unwritten sensor to which a protocol for a particular vehicle can be transferred. After that the sensor can be handled just like an OE sensor. Here we can offer you sensors from the current makers Alligator (SensIt), Schrader (EZ) and CUB to likewise be able to ensure the greatest possible coverage. We supply universal sensors that have already been preconfigured for the relevant vehicle. It is most important that you inform us of the exact vehicle data (make, model,type and year).

Multi-application sensors

These are likewise universal sensors, but certain protocols for various vehicles have already been preloaded. The sensor does not need to be reprogrammed but instead only the corresponding protocol for the vehicle in question need to be activated.

TPMS sensors from Interpneu


PLATIN Sens TPMS sensors are what are known as hybrid sensors, which already incorporate numerous OE original equipment protocols. The PLATIN Sens hybrid sensors cover approx. 90% of the market requirements.
In addition, a PLATIN Sens universal sensor is available which can be individually programmed. All PLATIN Sens sensors can be reprogrammed at any time with Ateq and Bartec diagnostic devices.

Alligator SensIt
Alligator SensIt

The updates for new vehicles can be obtained online and so you can always get the latest vehicle data very quickly if you have an Alligator programming pad.

The sensor can be programmed,overwritten and read with the current diagnostics data (such as Bartec, Ateq, Würth, etc.).


Offers wide coverage and can be programmed with Cub programming pads. It is also possible to read them using current diagnostics equipment (such as Bartec, Ateq, Würth, etc.).       

Huf IntelliSens

The vehicle protocols have already been set.

Schrader EZ

Schrader does not offer a special programming pad. Programming is done using current diagnostics equipment (such as Bartec, Ateq, Würth). Updates have to be obtained from the diagnosis equipment maker if updates are required for new vehicles.

Teaching-in the sensors

Regardless of whether it is an OE sensor or a universal sensor, it needs to be taught-in at the vehicle. The relevant teach-in process is defined by the vehicle maker.

There are three different ways of teaching-in a new sensor:

  • Self-learning of vehicles during a teaching-in run.
  • Manual teaching-in via the vehicle menu (the process is described in the vehicle manual).
  • Teaching-in via specific programming / diagnostics units and the OBD interface.

It is very important that you ensure before ordering the sensors (regardless of whether they are acquired separately, in connection with a wheel or as a mounted wheel) that you have the right equipment to also be able to calibrate the sensors on the vehicle.

It is therefore unavoidably necessary to have a corresponding diagnostics unit. The units can be obtained solely via the manufacturer or a parts wholesaler.

The EU energy label for tyres

The new EU tyre label helps consumers to decide in favour of a higher fuel efficiency class for their tyres. This can contribute to large reductions in running costs and emissions. Enhanced wet grip means greater road safety, and details of external rolling noise contributes to a reduction in traffic noise levels. 

The actual fuel savings and road safety depend heavily on the behaviour of drivers, and in particular on the following:

  • Eco-driving can significantly reduce fuel consumption
  • Tyre pressure needs to be regularly checked to optimise fuel efficiency and wet grip.
  • Stopping distances must always be respected.

Fuel efficiency class

Less rolling noise saves fuel and cuts CO2. This property is assigned to classes A to E.

Wet grip class

Wet grip is assigned to classes A to E. Wet grip is crucial to safe driving. For instance, the difference between class A and class E braking distances is 18 m.

External rolling noise class

The label presents the volume in dB and the class A (quieter), B, or C (louder). The noise emitted by tyres affects the total noise levels emitted by the vehicle.

Snow grip

The snowflake symbol confirms that the snow tested tyre keeps within the 3PMSF limits (type approval).
