Bead wire is the steel wire made of high-carbon steel whose surface is plated with red copper or bronze. By improving bead wire s strength and antifatigue property within the same intensity of tires. it can decrease the consumption of bead wire and weight of tires, and also reduce rolling resistance and save energy and costs of tires.
Tire bead wire is a type of tire skeleton material, which is made of high carbon wire rod and is applied to manufacture of various tires for bikes, motorcycle, cars, trucks as well as other vehicles.
