Sunny SN3870. FEATURES AND BENEFITS: All weather traction; High speed controllability; Reduced road noise levels; . OVERVIEW: The Sunny SN3870 is a performance and high performance, depending on the speed rating of the specific tire size, all season tire manufactured for passenger vehicles and SUVs.The model provides great all weather traction and hydroplaning resistance. The directional tread pattern and the all season compound increase the dry, wet and winter weather performance. The tread elements offer good grip on the road surface throughout the year, while the compound maintains its all weather flexibility. The straight and wavy circumferential grooves prevent hydroplaning by dispersing water and slush from beneath the footprint. In this manner, the tire guarantees first-rate traction all year.The tire's tread design and internal structure improves its controllability. The solid continuous center rib keeps the tire's road contact at all times, which boosts the steering responsiveness and driving stability. The steering becomes faster and more precise in its response to the driver's commands, while the structure is stabilized against the driving pressure affecting the model. The optimal shoulder tread block sequence increases the number of biting edges gripping the road surface. This upgrades the cornering and maneuvering capability and power. The tire's internal structure features a jointless spirally wrapped full nylon cap ply that maintains the optimal tire shape under the high speed driving pressure. The prevention of deformation and the directional tread design's equal pressure distribution prevent heat build-up and enables the tire to perform at its greatest high speed capability.The SN3870 provides a quiet performance. The tread features a variable pitch sequence that lowers the road noise levels heard. This sequence negates the road and tread pattern noise generated by canceling out the soundwaves with a sound frequency it creates. This guarantees a comfortable and enjoyable driving experience. 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.
