This footprint ensures the tire's close surface contact in order to enhance the steering responsiveness and the driving stability. As a result, the tire has a quicker and more precise steering response to the towing vehicle's steering instructions, while the structure is secured against the driving pressure affecting the tire during the performance. The shoulder block pattern optimizes the cornering and maneuvering ability with the use of additional biting edges. This combination greatly improves the towing vehicle's control over the trailer throughout the drive.
