Kumho Ecsta XS

The Ecsta XS (eXtreme Street) is Kumho’s Extreme Performance Summer tire developed for passionate driving enthusiasts looking to make the most of their vehicle’s capabilities in competition, at the track or on the street. The Ecsta XS is designed to deliver Kumho's ultimate level of dry road performance while maintaining wet traction. Like all summer tires, the Ecsta XS is not intended to be driven in near-freezing temperatures, through snow or on ice. The Ecsta XS molds Kumho's high-grip synthetic resin enhanced tread compound into an asymmetric pattern that features wide outboard shoulders to deliver dry road responsiveness and cornering, along with a continuous center rib that offers linear handling and high-speed stability. Two wide circumferential center grooves and an inboard network of aggressive lateral aqua grooves enhance wet capability. The tire's structure includes two high-tensile steel belts 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. (XS pronounced ‘ek-ses for excess).
