Kelly Edge A/S. FEATURES AND BENEFITS: All weather traction; Longer lasting tread life; Improved controllability; Reduced road vibration levels; . OVERVIEW: The Kelly Edge A/S is a touring all season tire manufactured for passenger vehicles and SUVs. Kelly offers a 55,000 mile treadwear warranty with this model.The tire guarantees superb all weather traction. The tread pattern firmly grips the road surface in dry, wet and winter weather, providing great all weather driving safety. The wide circumferential and lateral grooves actively resist hydroplaning situations by evacuating water and slush from below the tire footprint. A safer driving experience is ensured in this way.The tire's footprint is stabilized thanks to its excellent road contact. This extends the tread life and boosts the model's controllability. The stabilized tire footprint prevents the tread elements from shifting, allowing the tread to evenly distribute the driving pressure along the tire's surface. The equal distribution of the forces of acceleration, cornering and braking prevents irregular wear patterns from forming across the tread area, which lengthens the tread life and tire usability significantly.The improved steering responsiveness and driving stability are also due to the stabilized footprint. The maintained constant contact with the road surface increases the driving stability and the steering responsiveness. As a result, the tire is secured against the driving pressure affecting it and its steering response to the driver's instructions is swift and precise. The tread design's shoulder tread blocks further enhance the controllability by boosting the cornering and maneuvering ability and power. The tread design's shoulder blocks provide additional biting edges in all weather and ensure a safer cornering capability.The Edge A/S offers a comfortable driving experience. The tread pattern's excellent traction and constantly maintained road contact decrease the road vibrations felt in the vehicle's cabin. The lowered road vibrations felt by the passengers while the tires are in motion guarantee an enjoyable 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.
