摘要： Provided is a pneumatic tire manufacturing method capable of improving the productivity of pneumatic tires each having surface fasteners in its tire inner surface, and of avoiding manufacturing a pneumatic tire having a deteriorated uniformity, as well as of preventing engagement elements of each surface fastener from being crushed. Also, provided is a pneumatic tire manufactured by the pneumatic tire manufacturing method. The pneumatic tire manufacturing method according to the present invention includes the steps of, in making a green tire having two-side fasteners in its tire inner surface in its tire circumferential direction, each two-side fastener including an engagement element group on both sides: covering the engagement element groups on first sides of the two-side fasteners with a protective rubber layer made of an uncured rubber; making a cylindrical first formed body on a making drum, with the two-side fasteners covered with the protective rubber layer being intermittently attached to an inner circumferential surface of the first forming body in a circumferential direction thereof with the engagement element groups on second sides of the two-side fasteners being interposed in between; bonding the first formed body to an inner circumference of an annular second formed body by compression through expanding the first formed body into a toroidal shape, and thereby making the green tire; and curing the green tire inside a mold of a curing machine while pressing the green tire from its inside by a bladder.
