Designed for SUVs and 4x4s during the cold season, the WA-1 delivers outstanding stability and optimal grip on icy or snow-covered roads. Its widened tread maximises ground contact to enhance handling, while four longitudinal grooves efficiently expel water and slush. Rubber bridges between the tread blocks increase pattern rigidity, providing more precise steering. Zigzag sipes combined with a three-dimensional design boost traction and digging capacity in snow. Finally, the silica-enriched compound ensures superior traction and reliable handling, even in the most severe winter conditions.
