Dunlop Grandtrek AT20

The Grandtrek AT20 is Dunlop's Highway All-Season light truck tire that was developed for the drivers of pickups & sport utility vehicles. The Grandtrek AT20 was designed to deliver low noise, a comfortable ride, & year-round traction, even in light snow.
The numerous Grandtrek AT20 sizes developed for the aftermarket are branded with UTQG Ratings of 500 A B & have been designed to provide a balance of traits appropriate for today's lavish pickups & luxury sport utility vehicles, while the few Original Equipment Grandtrek AT20 tires developed several years ago are branded with UTQG Ratings of 300 B B & appear to place emphasis on low rolling resistance to increase the vehicle's fuel economy above poor weather traction & treadwear.
On the outside, the aftermarket tires feature Dunlop's advanced all-season compound molded into a tread design that combines independent intermediate & shoulder blocks with a continuous center rib to enhance dry traction & treadwear. Then crosscut sipes, wide circumferential grooves & deep lateral grooves provide the biting edges needed to enhance poor weather traction. On the inside, twin steel belts stabilize the tread while a Dimensionally Stable Polyester cord body & bead design promote ride comfort, handling & treadwear.
