All tires on the market pass a fundamental phase which is that of the track test. The tires are tested on all types of surfaces, providing extremely precise and detailed measurements with subjective and objective evaluations to the designers.
Experimental evidence is used by researchers to validate simulation mathematical models. The practical tests must take place under specific and repeatable conditions, in controlled places, known in the most technical aspects.
The asphalt conditions, constantly monitored, offer both tire and vehicle manufacturers an infinite number of possible maneuvers and tests in complete safety and controllable conditions.
Most of the test tracks are equipped with a bottom wetting system and one of the fundamental tests that are carried out is that of the grip of the tire on wet asphalt.
