It equally spreads the driving pressure out across the tread area, which prevents irregular tread wear from forming along the tire. The longevity of the even wear makes sure the tire can be used for an extended time. The shoulder tread design of the Scorpion STR lowers the road noise levels heard in the vehicle's cabin. It channels the soundwaves through the tire's footprint, preventing them from coming into contact with the tread elements, providing a quiet and comfortable driving experience.
