Tendency of a tire bead core to be rotated by the tire ply wrapped around the core, when the tire is expanded from a cylindrical or collapsed state to its normal toroidal operating state, particularly after the tire is cured, is inhibited, or eliminated by arrangement of the ply relative to the bead core which disposes the ply tension force direction at or nearly at the bead core center. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
