Hankook Ventus S1 Evo 4 X K137A ( 315/35 R21 111Y XL 4PR * SBL )

Premium Sport Performance, Engineered for the Future Enhanced Shoulder Grooves Wet braking performance is improved through expanded lateral shoulder grooves, which effectively secure air cavities and increase the contact area during braking or heavy loads. Additionally, specialized connecting bars on the shoulder blocks create a closed structure, minimizing noise levels during regular driving. Optimized Stiffness Pattern Maximized stiffness in the driving direction, particularly on the outer edges, enhances grip on dry roads. Improved Grip Performance with New Formula The Ventus evo delivers outstanding grip even on wet roads thanks to a new rubber compound infused with performance-enhancing resins. The advanced compound material increases grip by optimizing tire temperature during movement. Enhanced Cornering Stability The flattened shoulder profile increases the stiffness of the tire sidewall, ensuring maximum grip and driving stability, especially at high speeds.
