Hankook Kinergy 4S2. FEATURES AND BENEFITS: All weather traction; High speed controllability; Longer lasting tread life; High driving comfort levels; . OVERVIEW: The Hankook Kinergy 4S2 is a performance and high performance, all weather tire manufactured for passenger vehicles and SUVs. Hankook offers a 60,000 mile treadwear warranty with this model.All weather traction is improved with the silica compound and the detailed tread elements. The innovative compound with the natural silica ingredients optimizes the rubber flexibility of the tire during its year performance. This ensures the tires secure summer and winter weather traction. On the other hand, the directional tread design with the siping placement and serrated edge groove pattern upgrades the surface grip. They boost the dry, wet, and winter weather traction, including the tires safer drive on snow-covered surfaces. The angled later and circumferential grooves prevent hydroplaning in wet weather conditions.The footprint guarantees the surface contact at all times. The concave tie-bar pattern of the directional footprint works with the tires reinforced bead filler and steel belt structure to upgrade the steering responsiveness and the driving stability. As a result, the tire promotes a faster and more precise steering response to drivers commands, while the structure is secured against the pressure affecting the tire. The models reinforced structural elements maintain its ideal shape. The steel belts, balanced carcass and the bead filler keep the shape under the high speed pressure, while the silica compound avoids heat build-up across the tread area. This ensures the tires constant surface contact.The stronger structure, the tread design, and the compound upgrade the usability. The steel belt layer and the seamlessly reinforced belt cover work together to stabilize the tread area, effectively preventing tread flexing. This, plus the ideal tread design, allow the tires even pressure circulation, avoiding irregular wear along the footprint. The silica compounds rubber materials are wear-resistant, which greatly decreases the treadwear rate. The slow and even wear upgrades the service and tread life.The Kinergy 4S2 features a polyester carcass. This structure ensures the tires close surface contact, which absorbs the driving shock while the tires are in motion. Lowering the rolling resistance enables the tire to greatly decrease the road vibrations felt in the vehicles cabin. As road disturbances do not ruin the passengers driving enjoyment, the tire promotes a comfortable driving experience.All weather tires receive the three mountain peak and snowflake (3PMS) symbol for their exceptional winter weather performance. They are all season tires with extra winter weather grip, in order to guarantee safer year-round durability. This ensures their true and secure driving ability throughout the year. 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.
