PROBLEM TO BE SOLVED: To provide a manufacturing method for a motorcycle tire that inhibits a winding collapse of a band-like ply. SOLUTION: In a band forming process, a feed roller 21 of a band-like ply 10 is laterally moved in a drum axial direction along a roller traveling line L in accordance with rotation of a profile drum 20 so that the band-like ply 10 is spirally wound around on a band molding surface 20S. The interval D between the roller traveling line L and the contour line J of the band molding surface 20S is sequentially increased from the side of the drum equator toward the axial outside. Consequently, an angleαon the axial inside formed by a normal line N of the roller traveling line L at a point P on the roller traveling line L together with the contour line J is sequentially reduced from the drum equator side toward the axial outside.
