Dunlop’s Grandtrek line of tires are all season crossovers designed for light duty pick-up trucks and sport utility vehicles that meet the challenges of daily driving. The Grandtrek ST20 features circumferential tread grooves designed to help pump the water away from the tire footprint. This provides excellent traction in wet weather conditions. The Grandtrek ST20 is a Mud and Snow tire that incorporates an all-weather tread design to deliver year round traction with enhanced wet handling. Internally Dunlop’s Grandtrek features twin steel belts that are reinforced with a joint less band technology that provides strength and cushion providing a comfortable ride. The steel belts are spirally wrapped and placed on a polyester cord body to help provide cushion. The ST20 incorporates a 5 pitch technology to aid in noise reduction for a quieter ride in the mud and snow. The deep lateral grooves and crosscut sipes provide a biting edge that holds to the road surface in poor weather to provide added traction. The outer black serrated sidewall and raised black letter design creates a styling edge and finished look in this rugged mud and snow tire.
