The Blizzak LT is a Bridgestone tire specifically designed for medium-duty, heavy-duty, and commercial light trucks. It offers excellent load carrying capacity and traction for driving in cold, dry, wet, snowy, and icy conditions. The tire's rugged winter compound allows it to withstand harsh conditions and heavy loads often encountered by commercial vehicles. It has tie bars in the outboard shoulders to connect and stabilize the tread blocks for confident handling and resistance to irregular wear. The wide circumferential grooves help evacuate water and slush, while the zig zag center groove improves resistance to hydroplaning and enhances snow traction. It also features deep tread depths and independent tread blocks for better grip in snow, as well as a specialized winter compound and high sipe density for traction in wet or snowy conditions and on ice. The tire's internal construction includes a strong two-ply polyester cord casing, reinforced by two steel belts and a nylon casing ply. It meets the industry's severe snow service requirements and is branded with the three-peak mountain snowflake (3PMSF) symbol. To ensure optimal handling and tire performance, Bridgestone recommends installing Blizzak LT tires in sets of four and using them on all wheel positions. & The three-peak mountain snowflake symbol (3PMSF) is a designation given to tires that meet the industry's severe snow service requirements. This symbol indicates that the tire has been tested and proven to provide satisfactory traction in snowy conditions. When you see the 3PMSF symbol on a tire, you can have confidence that it will perform well in winter weather conditions.
