Designed to deliver Kumho's ultimate performance on dry pavement and cool confidence on wet, the Ecsta V720 delivers unusually long life for a tire that lives this fast. Like all summer tires, it's not intended to be 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.
