The tread's special funnel-shaped grooves actively avoid stone retention by preventing rocks from drilling into the tire's casing and shortening its service life. The stronger internal structure, on the other hand, maintains the ideal tire shape under the load and driving pressure affecting the model. This allows the tire to securely carry and withstand heavy loads with ease while the tires are in motion. As the tire does not deform under the pressure, it ensures a secure performing capability.
