Manufacturing method of pneumatic tire

A manufacturing method of a pneumatic tire comprising:

• a first step of laminating a plurality of belt plies so as to form a belt layer;
• and
• a second step of forming a belt reinforcing layer by spirally winding a rubber-coated reinforcing cord around an outer periphery of the belt layer,
• wherein the first step has a step of winding a first belt ply around an outer peripheral surface of a belt drum so as to form in a tubular shape by using the belt drum formed as a circular arc shape in which an outer peripheral cross sectional shape along an axial direction protrudes to an outer side in a diametrical direction, a step of arranging a rubber layer protruding to an outer side than an end portion in a width direction of the belt reinforcing layer, in an outer periphery of an end portion in the width direction of the first belt ply, and a step of winding a second belt ply which is narrower than the first belt ply, around an outer periphery of the first belt ply so as to form in a tubular shape, and
• wherein the second step arranges the end portion in the width direction of the belt reinforcing layer in an outer side than the first belt ply.
