Kelly Edge HP. FEATURES AND BENEFITS: All season tire; Longer lasting tread life; Increased controllability; Reduced road pattern noise; . OVERVIEW: The Kelly Edge HP is a performance and high performance, all season tire manufactured for passenger vehicles. Kelly offers a 45,000 mile warranty in all weather conditions.The special asymmetric tread pattern design and special tire compound boosts the all weather road gripping ability. They firmly grip the dry, wet and winter weather road surfaces to ensure a safer driving experience. The wide circumferential, lateral and swooping grooves effectively resist hydroplaning situations by eliminating water from below the tire footprint. The improved road gripping ability and hydroplaning resistance guarantee a safer year round driving experience.The tread pattern's wide center rib and the extra biting edges provided by the tread blocks increase the steering responsiveness and driving stability. They maintain constant road contact which boosts the steering response time and accuracy and stabilizes the tire against the driving pressure affecting it. The solid shoulder blocks enhance the cornering and maneuvering ability as they firmly grip the road surface and increase the number of biting edges in maneuvering. The upgraded controllability and cornering ability increase the driving safety in all weather.The tread pattern features a variable pitch sequence. This lowers the road noise heard in the vehicle's cabin while the tires are in motion. The tread design's pitch sequence creates a sound frequency that negates the pattern noise generated during the drive. The cancelled-out road noise guarantees a quiet and comfortable driving experience. The Edge HP promotes a longer lasting tread life. The tread design evenly distributes the driving pressure which avoids irregular wear patterns from forming across the tread area. The extended even wear and tire usability ensure an increased tire life, making the tire more cost efficient. 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.
