The tread's solid continuous center rib closely follows the road surface while the tires are in motion, which boosts the steering responsiveness and the driving stability. As a result, the steering becomes faster and more precise in its response to the driver's instructions, and the tire secures its structural stability during the drive. The stronger internal structure features a spiral jointless nylon cap or edge ply that reinforces the tire against the high speed driving pressure affecting the model. This allows the tire to perform at its greatest high speed capability and power, without allowing the tire to deform under the driving pressure.
