<p>A manufacturing method for pneumatic tire includes a process in which a raw cover (2) for a tire is formed, and a vulcanization process in which said raw cover (2) is inserted into a mold (3) and subjected to vulcanization molding. With the raw cover (2) inserted into the mol d (3), a sidewall rubber edge (E), whi ch is a boundary part between a bead chafer (13) and a sidewall rubber (12) that appears on an outer surface (2a) of the raw cover, is located further to the i nsi de of the ti re in the radi al di recti on than an inner core point (P1), which is the intersection point between the outer surface (2a) of the raw cover and an axial line (L1) that passes through a bead core (7) on the inner edge of the ti re in the radial direction. The manufacturing method is characterized in that an outer edge (15Bo) of a turn-up part (15B) of an insulation rubber (15) passes between a turn-up part (9b) of a carcass ply (9a) and the sidewall rubber (12), and terminates further to the outside of the ti re in the radial direction than the sidewall rubber edge (E).</p> |
