Confident Winter Traction The ESPIA EPZ provides superb traction even in the harshest weather conditions. Specially designed canyon sipes and a micro-glass fiber rubber compound allow the EPZ to "claw" the roughness of ice and stubbornness of snow in a non-studded alternative to the traditional winter tire. With sizes ranging from 13-inch to 17-inch, the EPZ covers many of today's popular OE fitments. The Espia EPZ is the perfect choice capable of conquering mother nature at her worst on a daily basis.
