Plural inner face grooves 40 are formed to tire inner faces of a tire frame member 17 formed from a resin material. The inner face grooves 40 are formed to a region from an inner separation point corresponding to a separation point of a bead portion 12 from a rim 20 as far as an inner end portion 30 IN corresponding to a tread end 30A of a tread member 30.

A repair boundary indicator for an inflatable tire is disclosed. The repair boundary indicator is located on the interior or the exterior of the tire to indicate the boundary of the area of the tire that can be safely repaired.

Provided is a tire vulcanizing bladder comprising fluororubber, wherein a plurality of grooves extending in a width direction are formed on a circumference of an outer surface of the tire vulcanizing bladder, and a plurality of recesses connecting the grooves to each other are formed between the grooves. Also provided is a pneumatic tire comprising one or more fluorine-containing particles having a maximum diameter of 1.0 ?m or more per area of 100 ?m.sup.2 of a tire inner surface, wherein a plurality of bladder ridges extending in a tire width direction are formed on a circumference of the tire inner surface, and a plurality of protrusions connecting the bladder ridges to each other are formed between the bladder ridges.

A pneumatic vehicle tire of a radial type of construction with a profiled tread (1), sidewalls (3), bead regions (2) and an airtight inner layer (4), which forms the inner side (4a) facing the interior space of the pneumatic vehicle tire, ribs (6) being formed on the inner layer (4), having been imprinted in it by a heating bladder introduced into the interior of the tire during the vulcanizing of the pneumatic vehicle tire in a tire heating mold, and a sound absorber (5) being provided so as to extend in an annular manner on a circumferential region (4b) of the inner side (4a) opposite from the tread (1).

Grooves (7) have been formed by the heating bladder at least in a partial region of the circumferential region (4b) of the inner layer (4a) on which the sound absorber (5) is provided.

Apparatus and method for manufacturing an air maintenance tire includes an air pumping tube assembly station constructing an air pumping tube sub-assembly, a tire preparation station for forming passageways in the tire to accept an outlet device of the air pumping tube sub-assembly, an air pumping tube sub-assembly installation station and a pressure regulator installation station. The air pumping tube sub-assembly inserts into an elongate tire groove opening, facilitated by groove-spreading apparatus.

A tire is provided with a tire frame member that is made from resin and includes: a bead portion; a side portion that is connected to an outer side of the bead portion in a tire radial direction and that has hole portions formed at intervals in a tire circumferential direction; and a crown portion that is connected to an inner side of the side portion in a tire width direction and that has a tread disposed thereon.
