Key Features & Benefits
-
Asymmetric Performance Tread: The outboard shoulder is designed for maximum rubber-to-road contact during hard cornering, while the inboard side is optimized for water evacuation.
-
3D Interlocking Sipes: These sipes increase biting edges for wet/snow grip while locking together under dry load to maintain tread block rigidity and steering precision.
-
Advanced Wet Safety: Four wide circumferential grooves work in tandem with lateral hydro-pockets to rapidly displace water, significantly lowering the risk of hydroplaning.
-
Quiet Comfort Technology: An optimized multi-pitch tread block sequence disrupts road noise frequencies, delivering a smooth, premium cabin experience.
-
Elite UTQG 560 AA A: Represents top-tier ratings for traction and temperature dissipation, combined with a durable treadwear rating for long-lasting performance.
