Wheel testing

Wählen Sie TÜV SÜD Schweiz AG

What are wheel tests?

Wheel testing involves a series of tests that are carried out to meet vehicle OEM requirements or the specifications of test standards on bending fatigue, radial fatigue, biaxial impact, energy absorption, radial impact or torsion.

Why are wheel tests important?

Independent wheel tests carried out by a certified test lab play provide various benefits to wheel manufacturers and their clients:

  • Evaluate the quality of your product and increase sales revenue
  • Meet individual safety, quality and performance requirements of OEMs and testing requirements for homologation, enabling export to key automotive markets
  • Ensure the consistent quality of your products, and use the provided test data for optimising the development of new wheel models
  • Gain recognition for your brand and strengthen your reputation among OEMs by providing comprehensive test results which ensure product safety

TÜV SÜD is your independent partner to conduct comprehensive wheel tests

TÜV SÜD is the biggest independent institute for tyre and wheel technologies in Europe. We operate advanced wheel testing facilities that are equipped to conduct the full scope of tyre and wheel tests. Our experts are highly trained professionals who work extensively with top automotive OEMs and suppliers worldwide. Through this experience, we have developed a strong knowledge of manufacturer and vehicle OEM requirements. We also have the expertise to conduct testing on special wheels that are not covered by any standards, such as wheels for trucks, agriculture vehicles and other special vehicles.

TÜV SÜD's wheel testing services

As a neutral, independent third-party Organisation TÜV SÜD provides you with the full scope of wheel tests according to standards, regulations and customer specified requirements.

We conduct wheel testing to the following test standards: StVZO, ECE, VIA, JWL, JASO, SAE, ISO, INMETRO, EUWA and AK-L08.

  • Wheel testing

Includes wheels for passenger car/light truck, truck and motorcycle, agriculture vehicles and other special vehicles.

  • Multi-axis wheel testing

Thanks to our new biaxial test rig, we can not only test wheels separately for fatigue, but also reliably assess their behavior in the wheel assembly and also the adjacent chassis components. For example, we can simulate real time programs on our test bench realistically, so that driving tests on the road to assess the wheel assembly can be partially substituted by a test bench test. The additional installation of a brake including real-time control up to the ABS control range allows the reliable simulation of important parameters such as different operating temperatures. The flexible design of the test setup also allows for the investigation of issues that could previously only be carried out in road tests and which, in addition to high material costs, also posed logistical challenges. The new test machine now effectively saves time and money also in these areas.

We offer:

  • Fatigue testing under highly realistic conditions
  • Development of programmes to test the setting behaviour of wheel bolts on the test machine instead of in drive tests
  • Reliable simulation of operating temperatures based on integration of a vehicle brake also, and in particular, for carbon and plastic wheels
  • Mapping of multi-axis real-time programmes to simulate operating loads
  • Multi-axis tests of wheel assembly including chassis stiffness
  • Extended tyre testing programmes, e.g. determination of rolling resistance under consideration of chassis influences (wheel alignment, wheel hub and wheel bearing) and high-speed testing under consideration of wheel alignment (setting of track and camber).
  • Type approval

  • Project management

    Control of development process and reporting to OEM
  • Other types of testing

    Testing of tyre pressure monitoring system (TPMS) according to ECE R64, testing and certification of tyre sealant and inflator packs and snap-in valves.
