Accelera Sigma ZR 84W XL

Accelera Sigma. FEATURES AND BENEFITS: Summer weather traction; High speed controllability; Reduced road noise levels; . OVERVIEW: The Accelera Sigma is a high performance summer tire manufactured for passenger vehicles.The tire promotes excellent summer weather traction. The summer tire compound and the directional tread pattern work together to boost the dry and wet weather road gripping ability. The directional tread design finds firm grip in warmer weather conditions with its optimal road contact. The summer compound prevents heat build-up and damage caused by the sun rays, while also maintaining the tire's flexibility in such conditions. The tread's multi-cone lateral grooves improve the water dispersing capability, which upgrade the hydroplaning resistance. The better summer traction and hydroplaning resistance ensure a secure driving experience.The model guarantees superb high speed controllability. The tread design's center tread area features a V-shaped pattern that keeps the tire's road contact at all times. This upgrades the steering responsiveness and driving stability. The steering becomes faster and more accurate, while the structure is stabilized against the driving pressure affecting the tire. The shoulder tread blocks heighten the number of biting edges that grip the road surface during cornering and maneuvering. They boost the cornering ability and power with their enhanced gripping capability. The tread design's even pressure distribution and the heat resistant tire compound enable the tire to perform to its highest capability in summer weather.The Sigma ensures a quiet drive. The special closed shoulder pattern lowers the road and tread pattern noise heard while the tires are in motion. The closed shoulders prevent airwaves from entering the tire's footprint and coming into contact with the tread elements. In this manner, the road noise is not generated and it does not reach the vehicle's cabin. This results in a comfortable and enjoyable performance. 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.
