Kumho Ecsta PA51

OVERVIEW

The Kumho Ecsta PA51 is a performance and high performance, depending on the speed rating, all season tire manufactured for passenger vehicles. Kumho offers a 45,000 mile tread wear warranty with this model. Kumho covers this tire model and size with its Road Hazard Warranty. This warranty is available for tires damaged by road hazards within the first 12 months after the purchase date, or until the first 3/32” of the tire tread wears away, whichever comes first! If this tire sustains road hazard damage (typically caused by nails, glass, or potholes) on its tread area, customers have a right to use the Road Hazard warranty for a Tire Replacement of an equivalent Kumho tire. To receive the Road Hazard warranty, customers with damaged tires must file a claim with Kumho Tires.

The tire promotes great all weather traction. The silica-based tire compound and the asymmetric tread pattern increases the tire's grip on dry, wet and winter weather roads. The silica in the tire's rubber material maintains its flexibility in various weather, including in colder temperatures. The asymmetric tread's siping and notch pattern helps improve the grip the tire has on the road surface. These tread elements heighten the number of biting edges gripping the road surface which guarantees a secure driving experience. The circumferential grooves prevent hydroplaning by dispersing water and slush from below the tire's footprint. The better traction and hydroplaning prevention guarantee a secure driving experience.

The model's controllability is enhanced with its tread pattern. The tread's continuous center ribs keep the tire's contact with the road surface at all times, which upgrades the steering responsiveness and the driving stability. The better contact with the road surface boosts the tire's steering response time and accuracy to the driver's commands, while it secures the structure against the driving pressure affecting the model. The tread's wider shoulder tread block pattern upgrades the cornering capability. These blocks increase the number of biting edges gripping the road surface to improve the cornering and maneuvering ability. The maintained road contact and optimal tire shape and the silica-compound's prevention of heat build-up work together to significantly enhance the high speed performance and driving ability.

The tire's balanced footprint and tread pattern advance the tread life. The maintained road contact upgrades the tire's contact with the road surface, which enhances the pressure distribution along the tread area. As a result, the driving pressure is evenly circulated on the tire's surface. This equally spread out force of acceleration, cornering and braking avoid the formation of irregular tread wear formations. The longer lasting tread life elongates the tire's usability making the tire more cost-efficient.

The Ecsta PA51 offers a quiet performance. The tread design features a special variable pitch sequence which decreases the road noise levels heard during the drive. The pitch phase shift of the tread ribs creates a unique sound frequency that lowers the road and tread pattern noise heard in the vehicle's cabin. While the tires are in motion, the road and tread pattern noise does not ruin the driving enjoyment of the passengers, which guarantees 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.
