The tire's exterior features a unique Tube Multicell tread compound that evenly pushes out the thin water layer created by icy roads. This tire is equipped with an in-depth block tread design with zigzag siping for superb winter traction. The tire's interior is held up by two steel belts that are reinforced with spiral-wrapped nylon that ensure the tire's shape at intense highway speeds. A polyester cord casing further ensres force and endurance while also maintaining optimal ride quality.
