The Eurowinter HS01 is designed to perform in the harshest of winter conditions with an improved compound over predecessor, the Eurowinter HS449. The Eurowinter HS01 features a new directional tread pattern and central transverse grooves that extend from the center area of the tread and expand in width toward the shoulders. These traits allow for better performance in snow and more efficient water dispersion — via wider exits — for improved wet grip and hydroplaning resistance.
