The Transforce AT is Firestone's On-/Off-Road Commercial Traction light truck tire developed for the drivers of multipurpose full-sized pickups, vans, sport utility and commercial vehicles looking for heavy-duty light truck tires that can combine traction on the highway, as well as at work jobsites and recreation areas. The Transforce AT is designed to provide on- and off-road traction in dry, wet and wintry conditions, including snow.Transforce AT radials feature a Long Link Carbon tread compound molded into a symmetric tread design that uses notched shoulders, independent intermediate tread blocks and multiple sipes to blend dry-road handling with poor weather traction. Wide circumferential grooves provide hydroplaning resistance while lateral grooves and multiple sipes provide the biting edges needed to enhance snow traction.The tire's structure includes twin steel belts reinforced by spiral-wrapped nylon to help maintain the tire's shape and enhance performance at highway speeds while a polyester cord body improves ride quality.
