Abstract:
Provided are: a tire production method and a molding system in which it is possible to use a reinforcing cord without waste and avoid a decrease in productivity when producing a tire comprising a reinforcing member that is wound around the tire multiple times in the tire circumferential direction in a state in which the reinforcing cord is continuous, or that is wound in the tire circumferential direction while extending in the tire width direction; and a tire. A previous carcass cord 15a is used to mold a carcass layer 15 while being supplied from one supply unit 3A to a molding drum 2; the tip of a next carcass cord 15b is fed out from another supply unit 3B, and the tip of the next carcass cord 15b is made continuous with the previous carcass cord 15a by a splicing mechanism 8 at the point when a prescribed length of the previous carcass cord 15a has been supplied; and molding of the carcass layer 15 is then continued while supplying the next carcass cord 15b to the molding drum 2 to complete the carcass layer 15.
