Americus Sport HP. FEATURES AND BENEFITS: All weather traction; High speed controllability; Longer lasting tread life; . OVERVIEW: The Americus Sport HP is a performance and high performance, depending on the speed rating of the specific tire size, all season tire manufactured for passenger vehicles. Americus offers a 60,000 mile warranty with this model.The tire promotes great all weather traction. The directional symmetric tread design and the special all season tire compound work together to increase the dry, wet and winter weather road gripping ability. The compound maintains its flexibility even in colder temperatures, while the tread firmly grips the road surface throughout the year. The wide circumferential and smaller, angled lateral grooves enhance the water and slush dispersing capability to improve the model's hydroplaning resistance. The upgraded all weather traction and hydroplaning resistance ensure a safer driving year round driving experience.The model guarantees first-rate controllability. The tread design features a solid center rib that keeps the tire's road contact at all times which boosts the steering responsiveness and driving stability. In other words, the steering becomes faster and more precise in its response to the driver's commands, while the structure is secured against the driving pressure affecting it. The directional tread design enables the tire to perform to its highest capability. It manages to evenly spread out the driving pressure to prevent the deformation of the optimal shape. The maintained shape promotes a secure high speed performance.The Sport HP offers a longer lasting tread life. The directional symmetric tread design manages to equally spread out the forces of acceleration, cornering and braking across the entire tread area. This actively resists the formation of irregular tread wear patterns across the tire's surface, extending the tread life and the tire's usability significantly. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
