The Momo W-1 North Pole offers excellent winter performance when it really matters. The directional model helps maintain road contact in winter, while circumferential grooves help evacuate water from the tread for better wet traction. The tire's central rib enhances handling and braking performance while increasing grip and providing greater stability. Zigzag sipes help improve bad weather traction by increasing the number of biting edges in contact with the road, while lateral V-grooves offer snow-packing capability for improved grip. With all sizes stamped with the Three-Peak Mountain Snowflake (3PMS) and designed for extreme snow conditions, the W-1 North Pole can withstand the harshest winters.
