The flat footprint and the ribbed design ensure the tire's constant road contact, upgrading the steering responsiveness and the driving stability. In other words, the tire is quicker and more precise in its response to the driver's commands. The strengthened structure allows the tire to secure the driving stability during its performance, while it also boosts the load durability. The reinforced structure keeps the ideal tire shape under the load and driving pressure, greatly upgrading the overall load capacity.
