PURPOSE:To obtain a tire excellent in appearance and durability by forming the embossed mark of a side wall part using a side wall strip wherein different color rubber is embedded in rubber for a side wall. CONSTITUTION:The side wall part 3 of a pneumatic tire is formed from a side wall strip 11 consisting of black rubber 9 for a side wall and different color rubber 10 having a color other than black. That is, the side wall strip 11 is formed by embedding the different color rubber 10 for forming an embossed mark 7 displaying a character mark, for example, a trade mark, a firm name or a product number in the base part 12 composed of the rubber 9 for the side wall. The embossed mark 7 is formed by vulcanizing a green cover tire in a vulcanizing mold having a recessed part for forming the embossed mark 7 provided to the inner surface thereof to mold a vulcanized tire and buffing the surface of the protruding part formed by the recessed part to expose the different color rubber. |
