Green tire and method for manufacturing pneumatic tire

A method for manufacturing a pneumatic tire comprising a step of building a green tire which has a surface layer defining a green tire surface, and a step of heating said green tire, wherein

• said step of building a green tire includes a step of forming said surface layer by a plurality of windings of at least one unvulcanized rubber tape having a tape width W1 of from 5 to 50 mm, in said surface layer,
• said windings are each overlapped with the adjacent windings, and
• a part of each of said windings is exposed on said green tire surface so that the exposed part has a width (Wa) in a range of from 50% to 80% of said tape width (W1),
• each said winding has a cross-sectional shape being substantially rhomboid and having one end at an acute angle corner exposed on said green tire surface and the other end at the opposing acute angle corner, and
• an angle theta of a diagonal line of said rhomboid drawn between the one end and the other end is not more than 30 degrees with respect to a tangential line to a profile line of said green tire surface at an point corresponding to said one end on said profile line,
• said profile line defined as a line smoothly contacting to exposed surface of each said exposed part, and
• said point corresponding to said one end defined as a point at which a line passing through said one end crosses at right angle to said profile line.
