The reinforced steel belted structure optimizes the tire shape, which enhances the driving stability, while the maintained road contact boosts the steering responsiveness and precision. The reinforced shoulder tread blocks increase the cornering ability and power. They heighten the number of biting edges that firmly grip the road surface during the drive to promote a secure cornering capability. The improved handling and maneuverability promote a safer high speed performance. The tire's internal structure also features a nylon cap ply that upgrades the model's durability. It prevents the deformation of the tire's structure under the high speed driving pressure, enabling the model to perform to its utmost capability in all weather.
