The Terreno Dry bridges the gap between file treads, and traditional all-conditions treads. The key to this is the unique angled "fish scale" design, that allows the center tread to roll extremely fast, yet offer traction when loaded in cornering and braking. Add the transitional height mid and side tread, and the Terreno Dry transitions as smoothly as it rolls. The exclusive 3C Graphene compound structure places 3 unique compounds where you need them most, adding to the performance. From gravel grinding to medium conditions cross racing, the Terreno Dry offers consistent performance.
