The first radial ply has a plurality of shoulders and lateral edges and each of the lateral edge portions is wrapped around a first core or a second bead core. The carcass crown has a first edge and a second edge. The second radial ply has a right side extending from the first edge of the carcass crown, and extending around the first bead core and a left side extending from the second edge of the carcass crown, and extending around the second bead core. Each of right and left sides of the second radial ply has a half width of the first radial ply. |
