This invention provides an air bladder for a safety tire capable of making a cylindrical form at an inflated state without adhering inner surfaces thereof to each other in the forming step, and particularly provides an air bladder for the safety tire formed by sticking a sheet-shaped rubber member 2 on a flat drum 1, folding back both widthwise ends 3 of the rubber member 2 and jointing both the ends 3 of the rubber member 2 at an outer diameter side with respect to the flat drum 1 to make a cylindrical form, characterized in that inner surfaces 4 of the rubber member 2 are not adhered to each other after both the widthwise ends 3 of the rubber member 2 are folded back.
