Tire Bead
* Tire bead bundles secure the tire to the wheel. They are large monofilament
steel cords that are wound together to form a cable or ribbon-type
configuration.
* The casing plies are looped around the bead bundles holding them in place.
* Bead filler, a rubber compound, is incorporated within the bead configuration
& extends up into the sidewall area.
* The rubber compound used on the outside bead area is usually a hard, durable
compound that withstands the rigors of mounting & chafing.
