On the outside, the Scorpion ATR features a silica-enhanced tread compound molded into a quiet-running, symmetric all-terrain type tread pattern. A virtual continuous center rib and large, stable outer tread blocks provide directional stability and steering response while interlocked independent tread blocks in the center tread area further provide even on-road wear and off-road traction. Sweeping central circumferential grooves and lateral shoulder grooves channel water to enhance wet traction and resist hydroplaning. The independent tread blocks are siped to provide extra biting edges that enhance off-road and snow traction. On the inside, twin steel belts reinforced with spiral-wrapped nylon cord support the tread area to provide predictable handling and precise high-speed control, while polyester cords stabilize the sidewalls and enhance ride quality.
