A modern tire may contain more than two hundred different raw materials. They're extremely complex constructions of steel, fabrics, rubber, and other substances designed to provide the best performance for the particular type of tire. The main body of the tire is constructed of rubber-coated fabrics called plies. The plies are covered with belts constructed of steel. The steel is covered with a heavily woven fabric, usually made of nylon. All of this is connected to a bead wire. The bead wire is a hoop-like structure made of steel that holds the tire on the rim. A layer of rubber that forms the sidewall and tread covers this structure. Contact your local tire dealer for more information on the construction of tires.
