ABSTRACT:
A bead core for a pneumatic vehicle tire that is designed to have its beads disposed on the radially inner periphery of a rim. The bead core is in the form of an endless ring that has an essentially round cross-sectional shape. To increase the bead-seating reliability, it is proposed that the inner core of the bead core be hollow or be formed by a lightweight ring that serves as a spacer element. At least one layer of load-carrying cords is disposed about the inner core. These load-carrying cords have a solid cross-sectional area or a hollow cross-sectional shape.
