What's the Difference Between the Bridgestone Blizzak WS70 and the LM-60?

When customers compare and search for what's available for their vehicle, occasionally they come across two different Bridgestone Blizzak models that may be the tire choice to handle their winter driving needs. In some cases, this can lead one to ask the obligating question: "What's the difference between the Bridgestone Blizzak WS70 and the Bridgestone Blizzak LM-60?" While both tires look very similar, the WS70 is a Studless Ice and Snow tire, where as the LM-60 is a Performance Winter / Snow tire.

The Blizzak WS70 features a softer dual-compound tread with Bridgestone's NanoPro-Tech silica-enhanced Tube Multicell compound layered on top of a standard winter compound. The Tube Multicell compound features thousands of microscopic tubes and cells uniformly distributed throughout the compound (which makes the rubber look like Swiss cheese when examined through a microscope) that wick away the water that often forms between the tire's contact patch and the surface of icy and snow-packed roads. Pores and tubes are constantly exposed around the tread as the tire wears. This flexible rubber compound boosts the tire's grip in cold conditions while the bite particles attached to the tubes scratch at packed snow and icy surfaces for traction.

The Blizzak LM-60, being a high performance winter / snow tire, is offered in a higher speed rating (H/130 mph). Since the current Multicell tread compounds used on Blizzak WS70 tires are not designed to support H-speed ratings, the Blizzak LM-60 uses a high silica content winter tread compound molded into a directional tread design that features independent tread blocks with 3-D zigzag sipes to disperse water away from the tire's contact patch, further enhancing grip. This combination provides hydroplaning resistance, greater driving and braking force on snow-covered roads.
