# Hankook Ventus S1 Evo 4 X K137A ## Premium Sport Performance, Engineered for the Future ed for drivers who demand precision and confidence, the Hankook Ventus S1 Evo 4 X K137A delivers a balanced blend of performance, safety, and comfort. Its advanced engineering focuses on delivering reliable grip across diverse conditions, making it a strong choice for high-performance vehicles and spirited driving. Expanded lateral shoulder grooves enhance wet braking by improving water evacuation and maintaining contact under pressure. This contributes to shorter stopping distances when it matters most. At the same time, the closed shoulder block structure reduces road noise, offering a quieter ride without sacrificing traction. A newly developed rubber compound with performance resins optimizes grip by managing tire temperature efficiently, ensuring consistent performance in both wet and dry conditions. The reinforced sidewall and flattened shoulder profile provide increased stiffness, improving cornering stability and responsiveness, especially at higher speeds. This tire excels in delivering a secure, dynamic driving experience while maintaining everyday comfort and durability.
