The Ecsta V720 is Kumho’s Extreme Performance Summer tire developed for passionate driving enthusiasts looking for a tire that was bred for performance and domesticated for civil society. Because its design focus is street use and specifically to excel in the short runs seen during autocross competition, the Ecsta V720 should not be driven on a race track. In addition to delivering Kumho’s ultimate performance on dry pavement, the Ecsta V720 provides cool confidence on wet. Like all summer tires, it’s not intended to be serviced, stored nor driven in near- or below-freezing temperatures, through snow or on ice.
Ecsta V720 tires mold Kumho’s super high-grip synthetic resin and ultra-fine carbon black enhanced tread compound into an asymmetric pattern featuring wide outboard shoulders to deliver dry road responsiveness and cornering, along with a continuous notched center rib that promotes control and high-speed stability. Crossed lateral grooves channel water away from the tread to enhance wet handling with outboard grooves that help clear water from the shoulder area for wet cornering, and the inboard grooves reduce hydroplaning and enhance wet braking.
The tire’s structure includes dual 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 provide handling control and positive feedback. The tire’s casing was developed using Kumho’s ESCOT “tension control optimization” technology that allows engineers to tune the bead, sidewall and shoulder tension to optimize footprint pressure distribution and uniformity. This results in less flexing and cooler operating temperatures that improve durability.
