Tyre testing

What matters to us?

Tyre testing is a vital part of tyre development at Goodyear. Tests on truck tyres are intensively carried out in Europe at Goodyear’s own facilities at the Goodyear Innovation Center Luxembourg as well at Mireval in southern France. Both these facilities have a range of test areas where different conditions can be reproduced; such as varying grip surfaces and skid pans.

In addition to this, Goodyear engineers carry out winter tyre testing in Arctic regions like Finland in the Arctic Test Center and drive the highways of Europe and beyond to replicate the extremes of conditions that transport companies experience in their regular operations.

As well as carrying out its own testing, Goodyear employs independent test companies such as the internationally renowned automotive testing company TÜV SÜD Automotive GmbH. Typically such tests focus on the comparison of tyres between manufacturers to demonstrate the outstanding performance of Goodyear tyres and the company’s other brands.

Field trials are a further important part of Goodyear’s testing regime. Typically truck, bus or coach operators will run Goodyear truck tyres in conjunction with their regular tyres to make comparisons over long periods in ‘real life’ conditions.

In developing a new truck tyre, Goodyear ensures that it meets 50 different performance criteria before any tyre is released for production. Each criteria covers a key performance area including:

  • Wet handling
  • Wet braking
  • Dry handling
  • Cornering grip
  • Durability
  • External noise
  • Wet traction
  • Stability at high speed
  • Rolling resistance
  • Mileage
  • Footprint contact pressure
  • High Speed
  • And many more…

All specific truck winter tyres are tested for specific performance factors including:

  • Ice traction
  • Braking on ice
  • Snow Grip Index (Acceleration test for truck tires on snow)
  • Snow traction
  • Braking on snow
  • Handling on snow
  • Hill climbing
  • And many more...

It is important to remember that when developing truck tyres, in improving the performance of one area another may suffer. An example of this is the relationship between rolling resistance and wear. Developing a tread compound that lowers rolling resistance – for improved fuel consumption - will typically reduce tyre life because of faster tread wear. So the real skill is to make improvements without negatively affecting another area and this is what Goodyear is very successful in doing.
