Accelera Phi 255/40R18 ZR 99Y XL AS A/S All Season Tire

Accelera Phi. FEATURES AND BENEFITS: Quiet driving experience; Fuel efficient tire; All weather traction; Enhanced controllability; . OVERVIEW: The Accelera Phi is a high performance, all season tire manufactured for passenger vehicles and SUVs.The tire’s tread design and tire compound ensure a more fuel efficient drive. The lightweight compound and the dynamic medium lateral grooves work together to decrease the tire’s rolling resistance. The rolling resistance is the pressure affecting the tires that determines how much energy the vehicle needs to maintain the tires in motion. The lower the rolling resistance the less the vehicle’s fuel consumption and CO2 emissions will be. This makes the tire environmentally friendly and fuel conscious at the same time.The tire offers excellent all weather traction. The all weather tire compound and dual zone asymmetric tread design enhance the dry, wet and winter road gripping ability. The compound keeps its flexibility in various temperatures, while the asymmetric tread breaks the tire up into a dry and wet/winter weather zones. These guarantee exceptional traction in all weather situations. The five wide circumferential grooves actively avoid hydroplaning by eliminating water and slush from below the tire footprint.The model is easily controlled. The driving stability and steering responsiveness are guaranteed throughout the tire’s life. The straight center rib secures the model against the driving pressure affecting it, while the tread design’s stiff tread ribs ensure an increased steering responsiveness and precision. As a result, the tire is stable during the drive and its steering responsiveness to the driver’s commands is quick and precise. The tread design’s shoulder tread block sequences also boost the controllability by providing additional biting edges for cornering and maneuvering situations. In such cases, the tire firmly grips the road, increasing the cornering ability and power.The Phi offers a comfortable and quiet driving experience. The shoulder tread blocks create a variable pitch sequence that cancel out the road noise. The road noise is decreased while the tires are in motion, as the variable pitch sequence creates a sound frequency that negates it. The result is an enjoyable, road noise free drive. 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.
