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. ©2006 Crossroads
