Yokohama Advan Sport A/S. FEATURES AND BENEFITS: All season traction; Hydroplaning resistance; Longer lasting tread life; Precise steering responsiveness; Increased cornering ability; High speed uniformity; . OVERVIEW: The Yokohama Advan Sport A/S is a high performance, all season tire made for passenger vehicles and SUVs. Yokohama offers a 50,000 mile treadwear warranty with this model.The tire has exceptional all weather traction thanks to the silica based tire compound and the asymmetric tread design. It grips the road well in dry, wet and winter weather conditions and provides increased safety year round. The Z-shaped grooves improve its snow traction and winter weather road grip. The circumferential tread grooves help resist dangerous hydroplaning situations and enhance the wet traction further by eliminating water from below the tire footprint.The silica infused tire compound also extends the tread life. The excellent traction the tire has maintains constant road contact and it grips the road well in all weather conditions which helps regulate the tread wear. Irregular wear is prevented as the driving pressure is evenly distributed along the tread area due to the good traction. Since the tire does not wear out unevenly, its tread life lasts longer.The tire's high speed performing capability is due to its easy handling and its great maneuverability. The asymmetric tread pattern provides effortless handling and controllability by improving the steering responsiveness and accuracy. The better steering ability allows the tire to respond quickly and precisely to the instructions of the driver. The shoulder tread blocks in the tread enhance the cornering and maneuvering power and ability of the model. The additional biting edges provided by the shoulder tread blocks grip the road when maneuvering, offering a safer drive.The Advan Sport A/S's reinforced internal structure increases its high speed performing ability. The reinforcement in the structure improves the tire's uniformity and it maintains its shape under the high speed driving pressure. As the tire does not deform, it provides safety during maneuvering.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.
