A tyre for dry or damp asphalt.
The percentage of grooves is the minimum allowed by the FIA technical regulations to ensure the maximum duration and efficiency even in the most severe conditions. The square profile and the particularly rigid structure of the RX facilitate steering precision and a prompt response both on slow guided routes, and on fast routes with prolonged stress on the tyre and fast changes of direction.
It is available in two compounds for specific weather and asphalt conditions. In a softer compound for competitions at low temperatures, smooth or damp surfaces, where a good level of grip is required and where the tread rubber is not excessively stressed; in a harder compound for special stages that require consistent performance over long distances and at higher temperatures.
