The Scorpion ATR is Pirelli's On-/Off-Road All-Terrain light truck tire developed for pickup, crossover and sport utility vehicle drivers that want to combine on-road civility with off-road capability. The Scorpion ATR is designed to master long highway journeys, wet roads and the challenges of winter driving by combining paved road comfort and handling with rough terrain grip and maneuverability. 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 shoulder tread blocks provide directional stability and steering response while interlocked independent tread blocks in the center tread area further promote acoustic comfort, even on-road wear and off-road traction. Sweeping central circumferential grooves and lateral shoulder grooves channel water to resist hydroplaning and enhance wet traction. The independent tread blocks are siped to provide extra biting edges that enhance off-road traction on loose surfaces and in snow. The tire's internal structure includes twin steel belts reinforced with spirally wrapped nylon cord to support the tread area providing predictable handling and high-speed control, while polyester cords stabilize the sidewalls and enhance ride quality.
