Bead Wire, a critical component in tire manufacturing, is strategically located at the inner edge of the tire, playing a pivotal role in securing the tire to the rim and bearing the weight of the tire and various forces encountered during travel. Crafted from high-carbon steel, bead wire boasts exceptional strength and elasticity, ensuring the tire maintains stability and safety under diverse conditions.
The manufacturing process of bead wire is stringent, requiring precise control over the wire's diameter, strength, elongation, and surface quality. These characteristics ensure that the bead wire can tightly encase the tire's bead area, forming a robust structure that maintains the tire's connection to the rim even during high-speed travel and sharp turns.
The surface of bead wire is often subjected to special treatments, such as copper or brass plating, to enhance its corrosion resistance and ensure a reliable electrical connection between the tire and the rim. This is particularly important for tubeless tires, where the bead wire must create an airtight seal with the rim to prevent air leakage.
Moreover, the design of bead wire is optimized for various tire types and applications, ranging from passenger car tires to heavy-duty truck and off-road tires. This versatility is achieved through the use of different wire diameters, cross-sectional shapes, and reinforcement techniques, tailored to meet the specific load-bearing and performance requirements of each tire category.
