Kumho Tire Harnesses New Technology to Deliver Maximum Performance

April 1, 2025

Kumho Tire U.S.A. has long been on the leading edge of all-season and summer tire innovation - providing premium, versatile products that exceed the expectations of even the most exacting consumers, while staying ahead of what the market demands.

“The all-season and summer tire categories are constantly evolving, driven by changing customer expectations,” says Edmund Cho, CEO of Kumho Tire U.S.A.  “End users and our dealers require the best of the best, which is why we’ve elevated our all-season (A/S) and summer tire portfolios to new heights with the introduction of three (3) new ultra-high performance products.”

These include the Ecsta Sport, the Ecsta Sport S and the Ecsta Sport A/S tires, which push the boundaries of tire technology and performance to unprecedented levels; leveraging the latest in artificial intelligence-powered design, advanced manufacturing and state-of-the-art materials. KUMHO’s advanced tire materials include specially formulated compounds that give multiple performance benefits without any compromise or trade-offs.

Leading the expansion of KUMHO’s summer tire lineup are the new Ecsta Sport and Ecsta Sport S – each featuring KUMHO’s ‘Innovative Compound Technology’, that consists of next-generation polymers, increased levels of high-dispersable silicas and elevated levels of high-grip resins, which together deliver optimal wet/dry performance, including excellent wet braking, handling and tread life. 

In addition, the tires’ multi-performance design makes them ideal for high-horsepower vehicles driven at fast speeds. Dynamic inside and outside shoulders provide strength and high-speed stability, and a new capply design built into the tires helps generate stiffer cornering force. Super sport car drivers demand nothing less and KUMHO delivers on customer expectations like never before. 

Both the Ecsta Sport and Ecsta Sport S are electric vehicle-compatible, come with a 30,000-mile warranty; fitting wheels ranging from 17 to 22 inches in diameter.

Also new from KUMHO is the Ecsta Sport A/S, a tire that delivers ultimate performance in all seasons; a comfortable, refined, quiet ride with superb road-gripping traction when drivers need to accelerate. The Ecsta Sport A/S tire’s new, high-grip tread compound uses next-generation polymers, increased levels of high-dispersable silicas and heightened levels of high-grip resins. By using these state-of-the-art material technologies, KUMHO has optimized wet/dry performance with outperformed snow traction and tread life, which is especially important to sedan drivers who demand exceptional snow, wet and dry braking, handling and stability year-round. 

Wide and stiff outside cornering blocks add extra stability to the Ecsta Sport A/S, while 3D interlocking sipes minimize tread block movement, delivering extraordinary grip. The rounded edges of the Ecsta Sport A/S minimize noise to provide outstanding comfort and the tire’s longitudinal grooves help accelerate water evacuation. Available with a 50,000-mile treadwear warranty, the Ecsta Sport A/S tire features KUMHO’s K-Noise Defender Technology and also is compatible with electric vehicles and wheels ranging from 16 to 21 inches, with an extensive range of popular fitments and applications.

“KUMHO is constantly pushing the limits of tire technology, innovation and performance across the industry,” says Cho. “Our new UHP products will help consumers unleash peak performance of their vehicles at a competitive price and set a new standard for what all-season and summer tires can and should be.”
