The symmetric ribbed tread pattern closely follows the road surface throughout the year, which enhances the steering responsiveness and the driving stability of the trailer. In other words, the steering becomes faster and more precise in its responsiveness to the towing vehicle's instructions, while the structure is stabilized against the driving pressure affecting the model. The model's stability is further improved with the reinforced internal structure. This construction does not allow the optimal tire shape to deform under the driving and load pressure affecting it. This enables the tire to also carry and withstand heavier loads with ease, significantly improving its durability.
