Hankook 1034945 Dynapro Evo AS RA21 275/40R21 107Y All-Season SUV Tire

The Hankook Dynapro Evo AS RA21 is an all-season passenger SUV tire engineered for year-round performance, blending wet-weather confidence, cold-climate capability, and long-lasting tread life in a single premium package. Sized at 275/40R21 with a 107Y service description, it is purpose-built for modern performance SUVs and crossovers that demand both dynamic handling and all-season versatility.

Key Features:

• Wave and interlocking 3D sipes — designed with increased density and precision to minimize block deformation and maintain biting edges across varying temperatures and road conditions
• Shallow dashed grooves — segment tread blocks vertically while maintaining horizontal continuity, optimizing overall contact patch width and lateral stiffness for improved cornering response
• Dual reinforced belt package — two primary steel belts with an additional reinforcing belt pair layered on top for enhanced high-speed stability and casing durability
• High-silica compound with performance resins — advanced tread compound delivers reduced rolling resistance, improved wet braking, and extended tread life
• Cold weather compound — formulated to remain pliable in low temperatures, providing reliable traction on cold and lightly snow-covered roads
• Precisely adjusted chamfer depths — center and intermediate chamfers are tuned alongside strategically placed tie bars and sipes to balance ride comfort, noise reduction, and handling precision
• Optimized contact patch — square center and shoulder design with rounded lateral groove entries eliminates acute corners to reduce stress concentrations and promote even tread wear

The Dynapro Evo AS RA21 is Hankook's answer to drivers who refuse to compromise between sporty performance and all-season dependability, delivering confident handling in dry, wet, and cold-weather conditions throughout the tire's lifespan.
