Kumho Tire's Ecsta AST KU25 is a high performance tire. Advanced belt package design is constructed using high-tensile steel belt and jointless nylon cap ply to reinforce the tread area, assuring high speed stability. Ultra hard bead filler maximizes lateral grip and high speed durability. Outstanding all-season tread compound improves wear resistance and ride comfort. Specially designed jointless high strength bead wire increases load capacity and minimizes road surface vibration. The AST’s shoulder blocks feature a sharp leading edge and a rounded trailing edge to prevent heel and toe wear. The leading edge increases wet and snow traction by cutting through ice and water film. Rim protector in lower sidewall safeguards wheel against scratches and abrasions. The Ecsta AST combines exotic appearance, modern tread design and technology in one low-profile package, while delivering all-season, high performance grip and handling to the entry-level tuner enthusiast.
