Abstract: A method of assembling a tire carcass comprising applying a cord reinforced rubber ply to a toroidal-shaped former such that the edges of the ply are located on radially inner portions of the former, placing a circular bead component adjacent to each edge and stitching each ply edge to its said circular bead component to secure the ply edge in the region of the tire bead.

Abstract: A pneumatic tire comprises a ground contacting tread including a tread strip extending axially between tread edges and sidewalls extending radially inwardly from each tread edge to respective bead regions, the tread being reinforced by at least a first circumferentially extending breaker ply, characterized in that each sidewall is reinforced by a carcass half ply extending from a radially inward first edge in the bead region to a radially outward second edge in the tread axially between the center and adjacent edge of the breaker ply; the carcass half ply including one or more reinforcing elements wound continuously between the radially inner and outer edges of the carcass half ply and around the circumferential periphery of the tire.
