Key Features:

• Asymmetric Tread Design — Wide outer shoulder blocks, V-shaped grooves, and multi-depth siping work together to enhance cornering stability, handling precision, and steering response.
• Solid Center Rib — Maximizes contact patch surface area for improved steering responsiveness and straight-line stability.
• Four Circumferential Grooves — Channel water and slush away from the contact patch to reduce hydroplaning risk on wet roads.
• Full-Depth Siping — Maintains biting edges throughout the life of the tire, preserving grip in dry, wet, and light snow conditions as tread wears down.
• Nanometer Silica Tread Compound — Enhances grip on both wet and dry surfaces while reducing rolling resistance for improved fuel efficiency; maintains flexibility across a wide temperature range for true all-season performance.
• Large Shoulder Blocks — Increase tread rigidity to maximize rubber contact with the road for precise handling at higher speeds.
• Variable Pitch Technology — Optimizes tread block sequencing to cancel sound waves generated between the tread and road surface, delivering a quieter, more comfortable ride.
• Integrated Rim Protector — Guards wheels against accidental curb and road damage.
