This ultra-high performance tire with an asymmetrical pattern is designed for optimal contact patch. A solid center rib provides directional stability and large outside tread blocks give increased cornering abilities. Tire features and benefits:* Four main channels provide increased grip in wet road conditions* Solid center rib improves straight-line stability for an 'on-center' feel* Oblique lateral grooves featured in each inside tread block increases the ability to disperse water while in motion reducing hydroplaning* Large shoulder tread blocks are designed to be mounted toward the curb where majority of cornering force is exerted and remain rigid under stress for precise and predictable turning， especially for higher center of gravity vehicles* Finely sliced blocks on the inside shoulders reduce noise and allow water to flow out of the contact area
