Dunlop’s Highway All-season tire for light trucks and sport utility vehicles is the Grandtrek AT20. The Grandtrek AT20 has been designed to deliver a more comfortable ride, noise reduction, and year round traction, even in light snow. Grandtrek AT20 after-market tires are branded with UTQG Ratings of 500 A B and are designed to provide a balance of traits that are appropriate for today’s luxury sport utility vehicles and lavish pickups. The original equipment Grandtrek AT20 tires were developed to emphasize the low rolling resistance that was designed to increase vehicle fuel economy above average tread wear and poor weather traction and were branded with UTQG Ratings of 300 B B. On the outside the aftermarket tires feature crosscut sipes, wide circumferential grooves, and deep lateral grooves to provide the biting edges that are needed to enhance traction in poor weather conditions. The Dunlop’s all season compound molded into the tread design combines independent intermediate and shoulder blocks that enhances dry traction and tread wear with the continuous center rib. On the inside a Dimensionally Stable Polyester cord body and bead design promote a comfortable ride, tread wear, and excellent handling with the use of stabilization using twin steel belts.
