Arroyo Ultra Sport A/S. FEATURES AND BENEFITS: All weather traction; Enhanced high speed controllability; Reduced road noise levels; . OVERVIEW: The Arroyo Ultra Sport A/S is a performance and high performance (depending on the speed rating) all season tire manufactured for passenger vehicles.The tire promotes exceptional all season traction. The silica-enhanced tire compound and the directional tread design, with the optimized 3D siping detail, increase the dry, wet and winter weather traction. The silica-infused compound maintains the tire's wet and winter traction, while the tread elements and sipes firmly grip the road surface. The siping detail heightens the number of biting edges to boost the ice- and snow-covered surface performance. The tread's wide circumferential grooves, with the 3D groove walls, actively resist hydroplaning by dispersing water and slush from below the tire's footprint. In this manner, the tire ensures a secure year round driving experience.The model's high speed controllability is guaranteed. The continuous central rib maintains the tire's road contact at all times, which upgrades the steering responsiveness and driving stability. The steering becomes faster and more precise, while the structure is stabilized against the driving pressure. The special directional tread design with the optimized pitch width regulates the tire's high speed performance. It evenly distributes the high speed driving pressure along the tire's entire surface to provide a stable performing capability. The tread design's 3D zigzag siping detail and the compound's silica molecules work together to create friction at the moment of braking. As a result, the tire's braking distance is significantly shortened and the model offers a safer all weather performance.The Ultra Sport A/S features a variable pitch sequence on its tread design. The tread design lowers the road noise levels heard in the vehicle's cabin. The pitch sequence generates a sound frequency that negates the road noise created while the tires are in motion. In other words, the road and tread pattern noise is cancelled out before it can disturb the passengers' comfort. 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.
