About the Kumho ECSTA PS91

The Ecsta PS91 is a Super- high- Performance Summer tire from Kumho and is designed for the drivers of sporty coupes, performance sedans, and sports cars. The Ecsta PS91 is for drivers who are looking for a tire to deliver the performance that is equivalent to the capabilities of their high-end vehicles. Although the Ecsta PS91 tire delivers superb handling and high-speed performance in both wet and dry condition, it is a summer tire and should never be driven in temperatures near-to- freezing, on ice or through the snow. Kumho utilized a Formula 3 racing tire technology by combining Silica with Carbon Black Compound with Max Grip Performance Resin to give the Ecsta PS91 optimum performance potential. Jagged, continuous center rib and C-Cut 3D design improve block rigidity to deliver high-speed stability, better steering response and braking performance. 3D Dimple Design reduces thermal buildup and capitalizes on tread blocks performance to deliver improved durability through continuous use. The four wide circumferential grooves provide quick water evacuation from beneath the tire’s footprint. The tire's two wide nylon reinforcement cap plies boost high-speed capability to deliver better steering response, stability, and durability.
