The ContiCrossContact Winter is Continental's Light Truck Performance Winter tire developed for the drivers of powerful, heavy 4x4 vehicles. The ContiCrossContact Winter focuses on dependable dry road handling, wet road hydroplaning resistance and winter driving competence. The ContiCrossContact Winter tire molds Continental's advanced silica compound into an asymmetric tread design featuring large, stiff tread blocks on the outboard shoulder that use self-stiffening sinusoidal sipes to ensure directional control at highway speeds. Smaller, more flexible blocks in the center of the tread and on the inside shoulder feature biting-edge sipes to enhance grip on snow and ice. Flow-optimized shoulder patterns and wide circumferential grooves (three or four depending on the tread width) help resist wet road hydroplaning. The tire's internal structure includes twin steel belts on top of a polyester carcass. Selected high-speed sizes also feature spirally wound nylon reinforcement above the steel belts to resist distortion at high speeds and while cornering. ContiCrossContact Winter tires meet the industry's severe snow service requirements and are branded with the mountain/snowflake symbol. Install Continental ContiCrossContact Winter tires in sets of four only. Due to the traction capabilities of ContiCrossContact Winter tires, Continental recommends using them only in sets of four to provide the best handling characteristics and tire performance.
