The Ecsta MX molds Kumho's advanced silica tread rubber compound into a directional tread pattern that features massive, stable blocks to increase cornering traction and steering response, while four large, circumferential and multiple directionally aligned lateral grooves resist hydroplaning and enhance wet traction. The tire's structure includes two wide steel belts that are reinforced by spirally wound nylon to provide excellent strength, uniform ride quality, and high-speed capability while the sidewalls are tuned to resist lateral deflection and to provide handling control and positive feedback.
