The symmetric ribbed tread pattern and the tread's maximized surface area ensure a constant and close surface contact while the tires are in motion. In this manner, the tire is able to upgrade the steering responsiveness and the driving stability. The better road contact ensures the tire's steering response time and accuracy, precisely following the towing vehicle's instructions. It also secures the structural stability throughout the performance, further boosting the driving security. As a result, the tire ensures the towing vehicle's better control over the trailer during the drive.
