The reinforced jointless spirally-wrapped full nylon cap maintains the ideal tire shape under the driving pressure affecting the model. This prevents the tire shape from deforming during its high speed performance. As a result, the tire can easily withstand the driving pressure, which allows the tire to closely follow the road surface throughout the drive. This, along with the ideal directional tread design, enhances the steering responsiveness and the driving stability. The steering becomes faster and more precise in its response to the driver's instructions, while the structure is stabilized against the driving pressure affecting the model. In this manner, the driver maintains control over the vehicle throughout its performance.
