The Bridgestone Blizzak WS50 tire is a premium winter tire for a wide range of cars, minivans and other vehicles that need deep snow traction, packed snow grip and ice traction. With the Blizzak WS50, Bridgestone takes tire performance with their new Winterbiter technology. This is a special compound that helps disperse water to reduce the risk of slippage. The tread design utilizes flow-through grooves that help maintain good traction on wet and slush-covered roads while its zig-zag sipes and independent tread blocks provide the edges that help bite through snow. The result in an efficient, safe, and quiet drive on snow and ice, as well as when the winter roads are clear and dry.
