The ECSTA ASX (ASX for All-Season Xtreme) 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 & sedans by blending responsive handling with dry, wet & year-round traction, even in light snow.

On the outside, the ECSTA ASX molds a high technology silica & carbon tread compound into an asymmetric tread design that features large outside tread blocks for quick response & sporty handling with high volume circumferential & high angle slant grooves to resist hydroplaning & 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 & increase handling by remaining stable when cornering. ECSTA ASX tires feature twin, high-tensile steel belts with spiral-wrapped jointless cap & belt edge strips to stabilize the tread area enhancing handling, high-speed capability & ride quality while minimizing weight.

Kumho ECSTA ASX tires feature black sidewall styling with black letters reversed out of a circumferential serrated band. They are available in V-speed rated, 55-series, 15" diameter sizes & W-speed rated, 55-, 50-, 45-, 40-, & 35-series sizes for 16" through 18" wheel diameters.
