The surfaces used can be wet or dry and range from smooth concrete and cobblestones to abrasive asphalt and extreme off-road terrain. The test tracks thus replicate the diverse range of conditions applicable to all types of tyre, from those favoured by motorcyclists to those employed in civil engineering.

Ladoux:

Near Clermont-Ferrand, in France, where 35 kilometers of circuit covering 500 hectares reproduce the main types of surfaces and configurations encountered. More than 2300 people use it to explore all the technological fields required for tyres.

Almeria:

Almeria, in Southern Spain, covers more than 5000 hectares. The space available and exceptional climatic conditions for Europe mean that Earthmover Agricultural and Truck tyres can be tested in extreme conditions.

Laurens:

Laurens, in the United States, covers 700 hectares and is dedicated to studying products, designed for the North American market.
