These tread elements upgrade the steering responsiveness and the driving stability, by closely following the surface contact throughout the performance. In other words, the better road contacts the tire is able to improve the steering response time and accuracy to the towing vehicle's commands, while the structure is secured against the driving pressure affecting the tire. The shoulder block pattern with the zigzag sipes and lateral grooves generate additional biting edges, optimizing the cornering and maneuvering capability and power. This combination guarantees the towing vehicle's better control over the trailer during the performance.
