The Ecsta PS31 is Kumho's Ultra High Performance Summer tire developed for drivers who emphasize handling and performance in dry and wet conditions for their sports cars, sporty coupes and performance sedans. Like all summer tires, the Ecsta PS31 is not intended to be driven in near freezing temperatures, through snow or on ice.
A high-technology summer compound features High Dispersible Micro Silica for a more even distribution of silica throughout the contact patch and High Grip Resin to enhance dry and wet traction. The compound is molded into a directional tread pattern with a solid center rib for improved high-speed stability and 3D Dimple Design heat dimples help minimize heat buildup in the tread blocks, increasing durability for reduced wear. Optimized lateral groove angles resist irregular wear while maximizing water displacement during wet-weather cornering, and the four wide, circumferential main grooves work with diagonal-sipe microgrooves to evacuate water from the footprint for hydroplaning resistance.
The tire features a computer-simulated structure to provide uniform contact pressure for even wear, and the reinforced internal construction includes a two-ply polyester casing beneath twin wide, steel belts and two full layer nylon cap plies for improved impact resistance, high-speed handling and durability.
El neumático Ecsta PS31 de Kumho pertenece a la categoría: Ultra Alto Rendimiento Para Verano y fue desarrollado para conductores que hacen énfasis en maniobrabilidad y rendimiento, sobre superficies secas y mojadas, al conducir sus autos deportivos, cupé deportivos o sedán de rendimiento. Como todo neumático de verano, el Ecsta PS31, no fue diseñado para ser utilizado en temperaturas cercanas al nivel de congelación o superficies con hielo o nieve.
Un compuesto de caucho para verano de alta tecnología utiliza, "High Dispersible Micro Silica", para una distribución más pareja de sílice a través del área de contacto, además, utiliza una resina de gran agarre, "High Grip Resin", para mejorar la tracción sobre superficies secas y mojadas. El compuesto de caucho es moldeado en una banda de rodamiento con diseño direccional, que cuenta, con un segmento central sólido, para mejorar la estabilidad a velocidades elevadas. Un diseño tridimensional, "3D Dimple Design", ayuda a minimizar la creación de calor en los bloques de la huella para mejorar durabilidad. Canales laterales con ángulos optimizados, resisten el desgaste irregular, mientras maximizan el desplazamiento de agua al tomar curvas. Cuatro canales circunferenciales anchos trabajan conjuntamente con ranuras diagonales muy pequeñas en los bloques, "diagonal-sipe microgrooves", para evacuar agua de la huella y resistir el deslizamiento sobre agua (hydroplaning).
El neumático, Ecsta PS31, posee una estructura simulada en computadora, para proporcionar una presión de contacto uniforme y así obtener un desgaste parejo. La construcción interna reforzada cuenta con dos capas de poliéster por debajo de correas gemelas anchas de acero, además de dos capas completas de nailon, para mejorar la resistencia a impactos, maniobrabilidad a velocidades elevadas y durabilidad.

Keep them rotated and the tread wear and life was amazing. Road noise is noticeable (as expected) but low. Did really well in the northern california winter. Wet traction was great, powder snow was great but as the snow got deeper and into ice it got pretty bad. Even in 4wd my truck struggled to make headway. Would love to buy another set but price is becoming higher than I want to put forth.
Note: my driving is mostly on tight winding mountian highways and gravel roads. This was not an option in the drop down so do with that info as you like.

Excellent tread wear. Replacing them now at 50,000 and still would pass safety inspection. Tires are 7 years old and road noise has increased significantly since new. This is due to age of tire hardening and wear. Definitely the quietest road noise for this aggressive of a tire.
