Kumho Ecsta HS51. FEATURES AND BENEFITS: Summer weather traction; High speed controllability; High driving comfort levels; . OVERVIEW: The Kumho Ecsta HS51 is a performance and high performance, depending on the speed rating, summer tire manufactured for passenger vehicles.The tire offers excellent summer weather traction. The tread's asymmetric pattern, with the center ribs, siping detail and shoulder notches, and the high performance tire compound improves the model's grip in dry and wet weather. The compound actively resists heat build-up along the tread area, which eases the driving pressure off the tire and boosts its traction. The tread elements optimize the road grip in warmer temperatures. The four circumferential grooves prevent hydroplaning by dispersing water and slush from below the tire's footprint. The optimal road grip and stronger hydroplaning resistance ensure a secure summer weather performance.The model is easily controlled even at high speeds. The asymmetric tread design's ribbed pattern closely follows the road surface, while the compound ensures exceptional traction even at high speeds. This allows the tire to increase its steering responsiveness and driving stability. The steering becomes faster and more precise, while the structure is stabilized against the driving pressure affecting the tire. The special ribbed pattern upgrades the braking ability. They create friction at the moment of braking which significantly shortens the braking distance. The tread's closed notched shoulder pattern heightens the number of biting edges gripping the road surface. In this manner, they significantly boost the cornering and maneuvering ability and power and promote a safer high speed drive.The Ecsta HS51 also offers an enjoyable drive. The tread design lowers the road noise heard and vibrations levels felt in the vehicle's cabin. The asymmetric tread's variable pitch phase shift decreases the road and tread pattern noise with the sound frequency it generates. The ribbed pattern closely follows the road surface and absorbs the shock of driving during the tire's performance. In this manner, the road vibrations are not felt in the vehicle's cabin. This ensures a quiet and comfortable 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.
