The Kumho Ecsta KU31 is a performance tire designed for drivers seeking a balance of confident grip and reasonable tread life. It caters to owners of sports cars, coupes, and sedans who desire enhanced handling and a sporty driving experience.
The Ecsta KU31 utilizes a high-dispersion silica tread compound to broaden the rubber's operating temperature range, promoting consistent road contact in varying conditions. Its directional tread pattern features large, independent shoulder blocks, three solid center ribs, and four straight circumferential grooves. This design contributes to superior wet and dry grip, high-speed stability, and responsive handling. The four circumferential grooves also aid in efficient water evacuation, reducing the risk of hydroplaning.
With a UTQG treadwear rating of 340, the Ecsta KU31 aims to provide a satisfactory lifespan for a performance-oriented tire. The tire's internal structure incorporates twin steel belts reinforced by a spirally-wrapped, jointless nylon cap, enhancing ride quality and high-speed durability. The shoulder blocks are tilted into the direction of travel to improve grip and reduce worn tire noise. The tire also features a rim protector in the lower sidewall to safeguard wheels against scratches and abrasions.
