All Weather Performance - Improved traction and performance in all conditions is achieved through a modern tread design with see-through circumferential grooves which disperse water.Increased Grip and Traction - Improved traction in wet and dry conditions thanks to computer modelled shoulder sipes which help balance larger tread areas to increase stability and flexibility with biting edges.Improved Handling and Quiet Ride - Solid centre rib enhances steering and handling ability whilst the variable pitch tread design provides a quiet running tyre at highway speeds.
