The Transforce AT2 is Firestone's second-generation On-/Off-Road Commercial Traction light truck tire developed for the drivers of full-sized pickups, vans, SUVs and commercial vehicles looking for heavy-duty tires that combine traction on the highway with grip on the unpaved surfaces frequently encountered at jobsites. The Transforce AT2 is designed to provide on- and off-road traction in dry, wet and wintry conditions, including snow.The Transforce AT2 molds a tough, chip- and tear-resistant all-terrain compound into a symmetric tread pattern. The open shoulder design and independent tread blocks help deliver traction in loose terrain, and the deep, circumferential grooves effectively evacuate water from the footprint to increase hydroplaning resistance. Wintertime traction is aided by the deep initial tread depth and siping within the blocks that provide additional biting edges in the snow.Two high-tensile steel belts support the tread area, with a spirally wrapped nylon reinforcement ply to maintain the tire's shape and enhance performance at highway speeds. The durable, two-ply body casing is made from polyester cord to help improve ride quality.
