Blizzak WS-50 represents the second generation of Bridgestone's WinterBiter tires. So if you want to maximize all of your vehicle's winter capabilities, the Bridgestone Blizzak WS-50 will help provide the snow and ice traction you need. The tread design uses flow-through grooves to help maintain good traction on wet and slush-covered roads while their zig-zag sipes and independent tread blocks provide the edges to help bite through snow.
