A method for manufacturing a pneumatic tire, the method comprising:
- vulcanizing a green tire using a bladder having a coating layer formed by a release agent, wherein the release agent has a thickness, detected by an electron microscope, of 0.1 μm to 100 μm on an inner surface of a tread portion of the pneumatic tire after the vulcanization.
A method for manufacturing a pneumatic tire, the method comprising:
- vulcanizing a green tire using a bladder having a coating layer formed by a release agent, wherein an amount of silicon in the release agent detected by X-ray fluorescence analysis is 0.1 wt. % to 10.0 wt. % on an inner surface of a tread portion of the pneumatic tire after the vulcanization.
