The stronger nylon belt-edge internal structure manages to maintain the ideal tire shape under the load and driving pressure affecting the model. This enables the model to carry and withstand heavy loads with ease, which boosts the load capacity. The strengthened construction also stabilizes the tread area. It actively avoids tread flexing from creating unnecessary friction during the drive. In this manner, the tire is able to evenly distribute the driving pressure along the tread area, actively preventing irregular wear formations across the tread area. This greatly lengthens the model's service life.
