The asymmetric tread's surface contact upgrades the steering responsiveness and the driving stability at all times. In other words, the better road contact boosts the steering response time and accuracy to the driver's commands, while the structure is secured against the driving pressure affecting the tire. The durable compound and the steel belt structure work together to ensure the tire's secure high speed performance. They prevent heat build-up and maintain the ideal tire shape under the load and driving pressure, allowing the tire to be driven at its utmost high speed capability.
