Toyo Open Country A/T III is a revolutionary, according to the manufacturer, all-terrain tire for SUVs, light trucks, and crossovers that ensures dependable traction in off-road conditions, as well as responsive and predictable behavior on paved roads. In addition, this tire is characterized by increased acoustic comfort and high resistance to wear; this model can also be used as an all-season tire. The Toyo Open Country A/T III, designed to replace the Open Country A/T II model, and, possibly, the Open Country A/T Plus, was put on the market in 2020. The new model’s optimized and more aggressive tread design, coupled with newly-developed rubber compound, ensures great traction in various weather conditions, consistent handling response, short stopping distance on wet pavement, smooth and comfortable ride, as well as increased resistance to tear and resistance to puncture, essential for All-Terrain tires. The tread pattern of the Toyo Open Country A/T III has more vacant space for self-cleansing, which improves the traction in off-road conditions, increasing the rigidity of the tread blocks for better road-holding ability and maneuverability, as well as preventing uneven treadwear. The increased width of the lateral sipes enhances the tire’s grip on all surfaces, including snow. The 3D wave-shaped sipes also serve to increase the tire’s resistance to wear, at the same time boosting the traction on snow and wet pavement. The Toyo OPAT III ability to handle the harshest of off-road conditions is ensured by the rigid shoulder blocks, arranged in a staggered order, with a multitude of biting sipes.
