The ribbed block pattern maintains the surface contact while the tires are in motion, enhancing the steering responsiveness and the driving stability. In this manner, the tire is quicker and more precise in its response to the driver's commands, while the structure is secured against the driving pressure affecting the tire. The shoulder block pattern with the siping placement enhances the cornering ability. They provide additional biting edges, firmly gripping the road surface at all times, optimizing the maneuvering capability.
