The Wrangler SR-A is Goodyear's Highway All-Season tire developed for the drivers of pickup trucks, crossovers and sport utility vehicles. Extensively used as Original Equipment on a wide range of popular light trucks, the Wrangler SR-A is available in a comprehensive range of 15" through 20" rim diameter sizes. The Wrangler SR-A is designed to reduce noise, vibration and ride harshness while providing all-season traction, even on gravel roads and in light snow.The Wrangler SR-A features Goodyear's WetTrac Technology that molds an enhanced wet traction tread compound into a symmetric tread design which combines independent tread blocks, wide circumferential grooves and hundreds of zigzag sipes to promote traction in wet and wintry conditions. The wide circumferential grooves help move water through the tread for wet traction while self-cleaning lateral grooves in the shoulders help evacuate water, mud and snow.The tire's internal structure includes twin, high-tensile steel belts on top of a polyester cord casing. Heavy-duty LT-metric-sized Load Range D & Load Range E tires are reinforced with spirally wound nylon to promote strength, even wear and extra durability.
