Kumho Ecsta STX 275/55R20, All Season, Performance tires.

Features and Benefits: All weather traction; Enhanced controllability; Comfortable performance; Kumho Ecsta STX TiresThe Kumho Ecsta STX is a performance and high performance, all season tire made for SUVs. The tire enhances the all weather traction with the special directional tread design and the all season compound. These elements ensure the tire's safer year round performance. The tread elements provide additional biting edges to grip the road surface, while the compound keeps the rubber flexibility in versatile temperatures. This combination significantly boosts the dry, wet and winter weather driving safety levels. The tread's wide groove placement channels water and slush from the footprint, avoiding hydroplaning. The strengthened internal structure and the tread design also improve the controllability. The Jointless Cap Construction maintains the ideal tire shape under the driving pressure, while also strengthening the structural stability while the tires are in motion. This structure enables the tire to securely perform at high speeds without the shape's deformation under the pressure. The tread's close and constant surface contact manages to increase the steering responsiveness and accuracy. The tire manages to improve the driver's control over the vehicle throughout its performance. The Kumho Ecsta STX improves the comfort levels as well. The tread features a variable pitch tread block sequence which successfully lowers the road noise levels. This pattern generates a sound frequency which negates the soundwaves before they are heard in the vehicle's cabin. As a result, the tire does not allow the model to unnecessarily disturb the passengers while the tires are in motion. This promotes 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.
