Tire Wire

Also known as bead wire, tire wire is made from silicon-killed, hot-rolled, Stelmore-cooled, high-carbon (0.65%-0.80%) steel rod drawn to 0.96-2.00 mm in diameter. Tire wire is used to reinforce the bead area of a pneumatic tire. Bead wire is typically bronze-coated; however, some manufacturers produce brass-coated bead wire.
