Hankook DYNAPRO EVO AS RA21

Overview of Hankook DYNAPRO EVO AS RA21

The Hankook Dynapro AS is a high-performance summer tire engineered for SUVs, crossovers and light trucks, delivering a refined balance of stability, durability, comfort and year-round capability. Designed with Hankook’s road-focused engineering technologies, it provides confident handling and reliable performance in a wide range of driving conditions.

At the core of its design is precision-tuned driving performance, with responsive stability built into every component. The Wave and InterLocking Band 3D sipes, featuring increased density and optimized depth, minimize tread block deformation under load. This enhances steering response, directional stability and braking performance, especially during high-speed driving.

Cornering performance is further improved through shallow, dashed grooves that vertically segment the tread blocks while maintaining horizontal continuity. This design evenly distributes rigidity across the outer shoulder blocks and increases the effective tread width, resulting in greater stability, sharper handling and improved cornering control.

The Double Up construction uses two reinforced steel belts with an additional layered pair on top, increasing overall durability and resistance to deformation. This advanced structure helps maintain tread shape, reduce wear and ensure consistent performance across various road conditions.

For wet driving, the Dynapro AS features an optimized void ratio, allowing efficient water evacuation without sacrificing directional rigidity. Its all-season compound enriched with high silica and performance resins improves grip and braking on dry and wet roads, while maintaining flexibility in cooler temperatures for dependable all-season traction.

Ride comfort is enhanced through an optimized groove and shoulder design. Expanded lateral grooves on the inner shoulder combined with a closed outer shoulder trap resonance within the grooves, significantly reducing high-frequency road noise. A carefully optimized contact patch promotes even wear and extended mileage, delivering a quiet, smooth and long-lasting driving experience.
