The ESPIA EPZ II ensures driving confidence in the harshest winter conditions. Using the latest technology in tread design, compound and construction, the EPZ II is an excellent blend of winter performance and longer tread wear. The zigzag shape of the main groove is designed to provide resistance to hydroplaning while the tread notches create biting edges for traction on snow and ice. The ESPIA EPZ II is specifically designed for the most unforgiving winters.
