The Ecsta ASX (ASX for All-Season Xtreme) (KU21) is a member of Kumho's race-proven Ecsta high performance tire family. It is an Ultra High Performance All-Season tire that was developed to meet the needs of the drivers of sports cars, coupes and sedans by blending responsive handling with dry, wet and year-round traction, even in light snow. On the outside, the Ecsta ASX molds a high technology silica and carbon tread compound into an asymmetric tread design that features large outside tread blocks for quick response and sporty handling with high volume circumferential and high angle slant grooves to resist hydroplaning and enhance wet traction. Constant contact center blocks help reduce noise while providing continuous road contact to improve straight-line stability. Internally, Ecsta ASX tires feature Kumho's Dynamic Casing Shape Technology that controls casing tension throughout the tire. This allows the Ecsta ASX to increase ride comfort by absorbing bumps and increase handling by remaining stable when cornering. Ecsta ASX tires feature twin, high-tensile steel belts with spiral-wrapped jointless cap and belt edge strips to stabilize the tread area enhancing handling, high-speed capability and ride quality while minimizing weight.
