GRANDTREK AT20

Highway All-Season

Overall Rating (8.3)


The Grandtrek AT20 is Dunlop's Highway All-Season light truck tire that was developed for the drivers of pickups and sport utility vehicles. The Grandtrek AT20 was designed to deliver low noise, a comfortable ride, and 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 and have been designed to provide a balance of traits appropriate for today's lavish pickups and 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 and appear to place emphasis on low rolling resistance to increase the vehicle's fuel economy above poor weather traction and treadwear.

On the outside, the aftermarket tires feature Dunlop's advanced all-season compound molded into a tread design that combines independent intermediate and shoulder blocks with a continuous center rib to enhance dry traction and treadwear. Then crosscut sipes, wide circumferential grooves and 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 and bead design promote ride comfort, handling and treadwear.

Comments These are replacements for the original set that lasted over 60K miles. The first set served me well for both on and light off-road driving. My only complaint is that they were not available with the raised white lettering. I like that look... I may purchase something else next time around so that I can have white letters again.
