To provide a method capable of efficiently manufacturing a multicolored tire wherein a color other than a black color can be contained in at least an arbitrary region over a long period of time without deteriorating the performance of the tire.
The tire is manufactured by coating the surface of an unvulcanized tire with a coating solution prepared by dissolving or dispersing at least a color forming resin in a solvent and vulcanizing the coated unvulcanized tire. A mode wherein the coating solution contains a rubber component, a mode wherein the color forming resin has a lamellar structure, a mode wherein the color forming resin contains polyester and aliphatic polyamide, a mode wherein polyester is polyethylene terephthalate or polyethylene-2,6-naphthalate and aliphatic polyamide is 6-nylon and the color forming resin is fibrous, a mode wherein the cross section in the direction crossing the longitudinal direction of the color forming resin is circular or oval, a mode wherein at least a part of the surface of the unvulcanized tire is at least a part of a side wall, and a mode wherein at least a part of surface of the unvulcanized tire is at least a part of a tread part are preferable.
