The reinforced tread block design maintains the tread rigidity and stability which allows the tire to increase its road contact. This, along with the outer zone compound's excellent traction for handling, raises the tire's steering responsiveness and driving stability. The tire is quick and precise in its response to the driver's commands, while it is stabilized against the driving pressure. The tread compound's inner zone enhances the tire's performance by shortening the braking distance and advancing its acceleration ability. As a result, the driver is capable of controlling the tire with confidence in all winter weather.
