sentences:  The tire bead is a thicker section of rubber, and is reinforced with braided steel cable, called the Bead Bundle.The inner-most surface of the tire bead creates the air seal between the tire and rim on a radial-ply tire and a bias-ply tire.Often, the bead can become frozen to the rim after rusting or corrosion occurs, requiring the use of a bead breaker in order to be removed.
