The primary functions of a tire are to carry a load and to allow the vehicle to accelerate, brake and turn. But beyond its functions, a tire is chosen for the performance you expect from it, which is relative to your use.
It is the way a tire is designed that will make it perform better under certain conditions than others. And to achieve specific performance, it is the tread that plays a decisive role.
The sculpture's grooves on the tread surface are essential to perform. Depending on their design, they will be more effective in certain conditions, on snow, on dry or wet roads.
The tire's tread depth also plays a role in performance. For example, it is important for water drainage when driving on wet roads. This ensures that the tire maintains contact with the ground and postpones the aquaplaning effect to higher speeds.
