Winter Radial Studless 
Silica Compounds 
Serrated Black Letters 
The studless winter radial W400 features a wide footprint to provide a tenacious road grip, driving stability on dry roads and adhesive frictional force on snowy and icy surfaces. A unidirectional, V-shaped pattern provides high speed stability and excellent handling on wet surfaces. Multi-wave kerfs maximize the "Edge Effect" and enhance braking, accelerating and cornering performance. Optimum pitch arrangement minimizes pattern noise.
