Tire Features

All-Season Performance

Performance Handling

The asymmetric tread pattern helps provide a balance of wet and dry performance.

Steering Responsiveness

Unique bead fit system helps enhance force transmission between tire and wheel for superb driver feedback.

Refined Handling

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.
