Bead wire is a specialty steel wire used in the construction of tyre beads. The bead is the part of the tyre that sits above the rim and holds the tyre securely on the wheel. Bead wire provides strength and reinforcement to the bead, allowing it to maintain its shape and sealing properties under pressure.

Physical Properties and Composition
Tyre Bead Wire  is a high carbon, spring steel with excellent strength and fatigue resistance properties. It comes in various wire diameters depending on the tyre size, with dimensions typically ranging from 0.15mm to 0.6mm. It also has a special epoxy coating or zinc coating applied to prevent corrosion. This protects the wire from chemicals and abrasion damage during the tyre manufacturing and usage process.

In terms of composition, it contains 0.8% to 1.1% carbon for increased hardness and spring-back ability after deformation. It may also contain manganese, silicon and chromium in small quantities to enhance strength and ductility. The carbon content is balanced to provide an optimal mix of these desirable mechanical properties.
