Brake Booster. A new shape for the hind edge of the tread bar, which enhances deceleration on slippery surfaces using the sipes' design.
Canola-Silica Compound. Using a canola-silica compound in the tread improves the tire's wet grip and reduces rolling resistance without compromising the tire's good winter properties.
Sipe Activators. The sipe activators on the edge of the tire's tread pattern enhance the sipes' performance on the most slippery surfaces.
Wedge Siping. This sipe innovation offers good stability and winter grip for friction tires. The tooth-like, wedge-formed sipes form a dense network that increases the tire's grip surface.
Driving Safety Indicator, DSI Winter. The driving safety indicator on the center rib of the tire indicates groove depth. The numbers stamped on the tread show the remaining groove depth in millimeters. The numbers fade one at a time as the tire wears down.
Information Field. The tire's information field can be used to mark the correct inflation pressure and the tire's place on the car during the storage season.
The Mud Stopper. The mud stopper prevents damage to the tire by stopping dirt and other objects from getting caught between the tire and the rim. Available in 14inch and bigger sizes.
