The steel belt structure allows the tire to maintain the ideal tire shape under the load and driving pressure. As the tire does not deform under the pressure, it is able to carry and withstand heavy loads, increasing the load capacity. The ideal tread design also allows the tire to upgrade the steering responsiveness and the driving stability, which boosts the driver's controllability. The tread design also allows the model to prevent damage to the casing. The optimized circumferential grooves eliminate rocks stuck in the footprint, resisting stone retention and offering safer controllability.
