The Hankook Dynapro Evo AS RA21 is an all-season passenger SUV tire engineered to deliver confident performance across a wide range of driving conditions — from dry summer roads to wet surfaces and light winter weather. Designed for crossovers and SUVs, the RA21 blends everyday comfort with all-season versatility in a 265/40ZR21 fitment.

Key Features:

• Wave and Interlocking 3D Sipes: Increased sipe density and precision engineering minimize block deformation for consistent grip and even wear over the tire's life
• Shallow Dashed Grooves: Innovative block segmentation maintains horizontal continuity across the tread while optimizing overall width and structural stiffness
• Reinforced Dual Belt Package: Two primary steel belts with an additional reinforcing pair layered on top provide enhanced stability and high-speed durability
• High-Silica All-Season Compound: A next-generation compound blending high silica content with high-performance resins delivers improved wet traction and rolling efficiency
• Cold Weather Compounds: Formulated to remain pliable in cold temperatures, maintaining grip in near-winter and light snow conditions
• Precision Chamfer and Tie Bar Design: Strategically adjusted center and intermediate chamfer depths with precisely placed tie bars and sipes balance stiffness with biting edges
• Optimized Contact Patch: Square center and shoulder block geometry combined with removed acute corners on lateral grooves improve contact uniformity and reduce irregular wear
