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.
