Abstract: The present invention is to provide a runflat tire which can effectively inhibit both of pulling out of carcass cords and coming off of beads during running in the runflat state. A runflat tire according to the present invention comprises a carcass 4 toroidally extending over a pair of beads 5, a pair of sidewall portions 6 and a tread portion 7, and a reinforcing rubber layer 8 which has a crescent sectional shape and is arranged at the interior surface side of the carcass 4. The carcass 4 comprises at least one cord layers 3 including radial cord portions 15, which are radially-arrayed at a circumferential pitch P, and circumferential cord portions 16, which circumferentially connect respective inner ends of adjacent radial cord portion 15.

Abstract: Using a core manufacturing method, a green tire is obtained in which edge portions of a carcass ply are turned up at bead cores. An inner liner 40 is set on an external surface of a hard core 12, and a carcass 46 is formed thereon. A bladder 36 disposed inside the core is inflated, whereby edge portions of the carcass 46 can be turned up. Thereafter, conventionally known tire structural members such as a belt, a side tread and a top tread are set on, and a green tire is completed on the external surface of the hard core 12.
