The method comprises the steps of a) forming a carcass composed of a cured rubber material and b) overmolding, on the carcass, at least one thermoplastic elastomer material in order to finish the pneumatic tire.

A peristaltic pump chamber with shape memory for pressure adjustment in tires is provided and which is part of the tire or is adjacent to the tire wall or is a part of a vehicle wheel, in particular for tires with an inner tube, e.g. bicycle tires.

The invention presents a device and a method for placing and attaching a strip inside a tire. Specifically, the tire is positioned on a mounting in relation to a centering means, and an adhesive device is placed inside the tire. While the tire is rotated, the strip is moved inside the tire, wherein a pressure force is applied to said strip. The strip is driven at a linear speed greater than the rotation speed of the tire, thus producing an effect of compressing said strip, the length of which becomes less than the nominal length thereof, thus creating a space between both ends of the strip such that, after release, the strip scrapes the adhesive device, which is repositioned on said ends, thus simultaneously causing said ends to be attached end to end.

The present disclosure relates to a light-weight tire inner tube comprising a film tube with a wall thickness of 100 to 400 microns, pneumatic tires containing the light-weight tire inner tube, and related methods for manufacturing the light-weight tire inner tube. The film tube is comprised of a film material comprising at least one thermoplastic engineering resin and optionally at least one saturated elastomer, and the film material of the film tube has an oxygen permeability of 8-15 cm.sup.3 O.sub.2/m.sup.2.Math.per day at 25° C.

A pneumatic tire in which a sealing layer can be provided at a desired position on an inner circumferential surface of the tire is provided. The pneumatic tire (10) includes a tire frame member (12) formed in a circular shape and made of a resin, and a sealing layer provided by fixing a sealant housing member (34) internally filled with a sealant (38) to an inner circumferential surface of the tire frame member (12).

A tire includes: a tire frame member formed in a ring shape from a frame resin material, and including a pair of bead sections, a pair of side sections, and a crown section; a ring shaped bead core that is embedded in and joined to each of the bead sections, and that is formed by a single strand, or plurality of strands, of bead cord extending in the tire circumferential direction, and covered with, and joined to, a covering resin material; and an extension portion that extends from each of the bead cores in a direction that intersects with the tire circumferential direction when viewed from a tire side face, and that is joined to the tire frame member.

There is provided a tire comprising a tire frame that is formed of a resin material and has a circular form, wherein the resin material comprises a thermoplastic elastomer having a structure including a hard segment (HS) and a soft segment (SS), which repeat alternately, in which a number of repeating units in one molecular chain is from 2 to 10, each of the repeating units being a pair of the hard segment (HS) and the soft segment (SS), the thermoplastic elastomer having a number average molecular weight of from 45,000 to 160,000.

A tire is provided in which there is no detriment to the ease of work when fitting onto a rim and removing from a rim, even when the tire is provided with a sealing layer. A pneumatic tire (10) includes a tire frame member (12) formed in a circular shape and made of a resin, and a sealing layer provided by filling a cavity (34) formed inside the tire frame member (12) with a sealant (38).

To improve the rigidity of a join portion of a tire frame member. A tire includes: a toroidal tire frame member formed of resin and is formed by joining a plurality of tire pieces together in a tire width direction; a reinforcement belt layer adhered to the tire frame member, and that extends in the tire circumferential direction so as to cover a join portion between the plurality of tire pieces; and tread rubber provided at an outer side in the tire radial direction of the tire frame member and the reinforcement belt layer, and the reinforcement belt layer includes a cord that straddles the join portion between the tire pieces.

There is provided a tire including a tire frame that is formed of a resin material and has a circular form, wherein the resin material includes a thermoplastic elastomer having a hard segment (HS) and a soft segment (SS), in which only one unit of the soft segment (SS) is included in a single molecular chain, and both terminals of the single molecular chain are formed by the hard segment (HS), the thermoplastic elastomer having a number average molecular weight of from 12,000 to 24,000.
