The Dura Shield construction maintains the tire's optimized shape under all weather and road conditions. As the tire does not deform under the driving pressure, it prevents the driving pressure from concentrating on one area of the tread. This, along with the solid shoulder tread blocks, prevents irregular tread wear as they evenly distribute the driving pressure along the tread area. The tread design's full-depth sipes also increase the tread life as they do not wear out with the tread wear. Instead they provide traction and road grip throughout the tire's tread life.
