Yokohama's winter truck radial features a deep directional tread, special silica compound and wide twin zigzag tread for maximized traction in snow and ice. Silica tread compound and wide center tread means outstanding low temperature pliability for improved winter grip. Wide twin circumferential grooves deliver excellent lateral traction in the snow and channel water to prevent hydroplaning. Zigzag interior grooves provide more biting edges to cut through snow and increase traction. Segmented directional blocks criss-cross for strong snow grip. Angled biting edges aid in cornering and boosts snow grip.
