A method of manufacturing a pneumatic tire comprising a belt which is wound with a belt-under diameter D outside a carcass ply in a tire-radial direction, includes preparing a strip-like rubber-coated cord member where a plurality of belt cords which are arranged approximately parallel are coated with rubber and a width of the cord member in a lateral direction is D sin . The cord member is cut at the cord angle with respect to a longitudinal direction to cut out a belt forming member having a parallelogram which includes circumferential direction sides extending in a tire circumferential direction in a wound state and formed as cut portions and inclined sides extending parallel to the belt cord and defined as both side portions of the cord member. The belt forming member is wound into a circular cylindrical shape and joined the inclined sides which face each other to each other.

A method of manufacturing a pneumatic tire includes preparing a belt forming member formed of belt cords arranged parallel and covered with rubber. In a development state, the belt forming member is formed into a parallelogram, so that in a state wound with the belt cords extending in a direction inclined at a cord angle , the belt forming member is formed into a circular cylindrical configuration where a belt-under diameter D is not smaller than 940 mm and not larger than 960 mm and a belt width W is not smaller than 270 mm and not larger than 310 mm, and the cord angle , the belt-under diameter D and the belt width W satisfy a relationship of 0.577 DW/tan<1.07D. The belt forming member is wound and joined at a joint portion where the inclined sides are brought into contact with each other.

A belt cover layer is disposed in a tire, spanning between shoulder regions, and is formed by winding one belt cover material in a helical shape around a rotation axis on an outer side of the belt layer in a radial direction, the belt cover layer includes a lap winding portion between the shoulder regions, in which parts of circumferential portions, adjacent in a width direction, of the belt cover material wound in a helical shape are lap-wound in the radial direction, a width of the lap winding portion in the width direction is 3-30% of a width of the belt cover layer in the width direction, and in portions of the belt cover layer in the shoulder regions, the circumferential portions, adjacent in the width direction, of the belt cover material are wound with out being lapped in the radial direction.
