The reinforced internal structure's steel belts enhance the load and driving durability. The strengthened belt structure maintains the ideal tire shape under the load and driving pressure affecting the model, improving the load capacity. As the tire does not deform under the load pressure, which enables the tire to carry and withstand heavy loads with ease. This structure also helps prevent damage to the casing, preventing punctures, cuts and impact damage from harming the casing and shortening the tire's service life.
