The percentage of grooves on the RX tire complies with the minimum allowed by the FIA technical regulations to ensure maximum duration and efficiency even in the most extreme conditions. The square profile and rigid structure of this tire facilitates steering precision and prompt response.This construction is effective for both slow routes and fast routes with prolonged stress on the tire and fast changes of direction.
It is available in two compounds for specific weather and asphalt conditions. The softer compound is better suited for competition driving on smooth or damp surfaces, and at lower temperatures where a substantial level of grip is required. In these instances, the tread rubber would not be excessively stressed.The harder compound is reserved for special stages that require consistent performance over long distances and at higher temperatures.
