The Bridgestone Blizzak LM-60 RFT tire is a winter runflat performance tire for sedans and sport coupes for winter traction on snow and ice, and sporty handling on dry cold roads. It also has excellent grip on packed snow, good control in slush, and traction on wet road conditions even during high speed driving. This tire has the same tread pattern as the LM-60, but with the added benefit of extended mobility. This means you can continue to drive on a tire that has lost all the air pressure due to a puncture. All the runflat sizes are heavily siped for biting edges and enough space between the tread blocks to prevent the snow packing into the tread, and to disperse the slush and water. The Blizzak LM-60 RFT tire also has a high-silica rubber compound in the tread for long tread-life.
