Tire Features
Multi-Radius Tread Technology™ helps deliver superb dry handling while maintaining wet traction.
Flatter tread profile helps provide an enlarged contact patch for enhanced cornering capability.
The asymmetric tread pattern helps provide a balance of wet and dry performance.
Unique bead fit system helps enhance force transmission between tire and wheel for superb driver feedback.
Hybrid Jointless Band Technology™ helps maintain the tire's shape, enabling smooth performance at highway speeds, and helps prevent flatspotting after the vehicle is parked for extended periods.
Non-directional tread allows for tire rotation on staggered fitments common to high-end performance vehicles, which promotes long tread life.
