In this manner, the tire is quicker and more precise steering response time and accuracy to the driver's commands, while the structure is secured against the driving pressure affecting the model. The shoulder block pattern with the siping placement firmly grips the road surface with extra biting edges, optimizing the cornering and maneuvering capability during the performance. This combination promotes a secure handling throughout the performance.
