The Blizzak LM001 is Bridgestone's Performance Winter / Snow tire designed for the drivers of sports cars, sporty coupes and performance sedans looking to maintain their vehicle's appearance, handling and mobility during the winter months by providing traction on cold, dry, wet and snow-covered roads. The Blizzak LM001 features an advanced tread compound to enhance cold weather traction. This compound is molded into a directional design for improved evacuation of water and slush, aiding in confident grip and braking traction in cold, wet and wintry conditions. The Lamellen edge effect and 3D sipes improve winter traction without resorting to traditional metal studs. This allows Blizzak LM001 tires to combine winter traction with H-, V- or W-speed rated capability. Blizzak LM001 winter tires meet the industry's severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol. To help drivers know when it's time to replace their winter tires, Bridgestone molds Winter Wear Indicators (also known as Snow Platforms) into the Blizzak LM001's main tread grooves to identify when winter traction will be reduced due to the tire's tread wearing down to the point where the remaining depth becomes less effective at digging through snow, gripping icy roads or coping with slushy conditions.Install Bridgestone Blizzak LM001 tires in sets of four only. Due to the traction capabilities of the Blizzak LM001, Bridgestone recommends using Blizzak LM001 tires in sets of four to provide the best handling characteristics and tire performance.
