- 4D NANO DESIGN - features new compound advancements through biomass materials to help improve tread flexibility and adhesion while simultaneously reducing polymer heat generation. - 3D CANYON SIPES - interlock the shoulder blocks to resist wear commonly associated with crossovers due to their higher center of gravity. - ASYMMETRIC TREAD PATTERN - consisting of polygonal-shaped inside grooves that provide more edges to increase wet and snow traction, is combined with a high-rigidity outside shoulder rib that delivers the handling and stability necessary for CUVs. - ROAD HAZARD PROTECTION - Every CT60 A/S tire comes with FREE replacement for up to two years or for the first 3/32nds of tread life. (Restrictions apply, ask your retailer for details). - FOUR WIDE CIRCUMFERENTIAL GROOVES - resist hydroplaning by quickly evacuating water through the tread pattern providing secure contact with the road in heavy rain. - SILICA ENRICHED TREAD COMPOUND - delivers superior wear life and wet performance over a wide range of operating temperatures.
