The Ecsta XS (eXtreme Street) (KU36) 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)
El neumático Ecsta XS (KU36) de Kumho, pertenece al grupo Rendimiento Extremo Para Verano y fue desarrollado para conductores entusiastas apasionados, que buscan obtener el rendimiento máximo de sus vehículos, ya sea, en competencias, pistas o las carreteras. El Ecsta XS ha sido diseñado para proporcionar lo más reciente ofrecido por Kumho, en cuanto a, rendimiento sobre superficies secas, manteniendo la tracción sobre mojadas. Como todo neumático de verano, el Ecsta XS, no fue diseñado para ser utilizado en temperaturas cercanas al nivel de congelación o superficies con hielo o nieve.
El Ecsta XS utiliza un compuesto mejorado de resina sintética de fuerte agarre, moldeado en un patrón asimétrico en la banda de rodamiento, que cuenta con hombros externos anchos para proporcionar mejor respuesta en carreteras secas y al tomar curvas. Un segmento central continuo proporciona maniobrabilidad linear y estabilidad a velocidades elevadas. Dos canales circunferenciales centrales y una red interna de ranuras laterales agresivas mejoran la capacidad de agarre sobre superficies mojadas.
La estructura del Ecsta XS incluye dos correas de acero resistente a tensiones fuertes, reforzadas con nailon envuelto en espiral, para proporcionar una fortaleza excelente, manejo uniforme y capacidad de rodar a velocidades elevadas. Las paredes o flancos resisten la deflexión lateral y proporcionan maniobrabilidad controlada y mejor información al conductor.
