The directional tread design with the solid center rib maintains the surface contact at all times, which enhances the steering responsiveness and the driving stability. The ideal tread's shoulder blocks boost the cornering and maneuvering ability with extra biting edges. The directional pattern also helps improve the braking power by shortening the braking distance. The optimized pressure distribution along the tread area enables the tire to enhance the high speed pressure durability, further improving the high speed performing safety.
