Abstract: The invention provides a cured tread and a tire capable of controlling irregular wear of the tread. A base tire which is to be the base for the tire and a cured tread which is to be bonded to the base tire are molded separately, and they are integrated with each other to produce the tire. The tread is provided in its width (axial) direction with a plurality of grooves extending in its length (circumferential) direction. The thickness of the tread in a width cross section gradually decreases from the equator to the equator-side edge of the outermost groove located at an axially outermost position and gradually increases from the outer edge of the outermost groove outward in the axial direction.

Abstract: 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.
