Adapter for a rolling assembly comprising a tire, and a rim having two rim seats and two rim flanges. The adapter has an axially inner end mounted on the rim seat and comprises an inner reinforcing element, an axially outer end that comprises an outer reinforcing element, a body that connects the two ends to form a single piece. A substantially cylindrical adapter seat is configured to receive a bead, and is situated at the axially outer end of the body. An adapter bearing face is substantially contained in a plane perpendicular to the rotation axis, and situated on the axially inner face of the axially outer end. The reinforcing element of the axially outer end is entirely situated axially outside the bearing face. The body comprises, opposite the adapter seat, an annular seat reinforcer. The inner wall of the tire is covered by a layer of a self-sealing composition.

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 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).

A sealant layer assembly which allows a sealant layer to be applied on a tire outside of tire production plants. The assembly comprises a sealant layer to be applied on the surface of an inner liner layer facing the inner cavity of a tire, a net layer arranged on a first surface of the sealant layer, and at least one non-stick protective layer arranged either on a second surface of the sealant layer opposite the first surface or on the net layer.

A polymer blend including an organic polymer with a reactive silicon-containing group which gives cured objects excellent elongation property and stress relaxation, a composition including the polymer blend, a specific filler, and a curing catalyst, a sealant including the composition; and a sealant for tires, are provided. A polymer blend including an organic polymer with a bifunctional reactive silicon-containing group of a specific structure is mixed with polyoxyalkylene (A). Polyoxyalkylene (A) has an average molecular weight of 13,000 or higher and 100,000 or lower, a reactive-silicon-containing-group equivalent Eqa of 0.010 mmol/g or more and 0.29 mmol/g or less, and contains more than one silicon-containing group per molecule and polyoxyalkylene (B). Polyoxyalkylene (B) has an average molecular weight of 3,000 or higher and 25,000 or lower, a reactive-silicon-containing group only at one end, and a reactive-silicon-containing-group equivalent Eqb of 0.03 mmol/g or more and 0.58 mmol/g or less.

The present disclosure relates to a tire comprising a sealant layer and an acoustic absorbent layer, and the tire comprises an acoustic absorbent layer positioned inside the tire, a sealant layer positioned between the inner surface of the tire and the acoustic absorbent layer, and applied to the inner surface of the tire, and a film layer positioned between the acoustic absorbent layer and the sealant layer.

The tire may enable a sealant layer applied to the inner surface of the tire to perform a self-sealing process in case of puncture, may have the noise reduction performance by comprising an acoustic absorbent, and not only may prevent micro-fragments of the acoustic absorbent from deteriorating the function of the sealant, but also may maintain the noise reduction performance even when a nail reaches the acoustic absorbent by penetrating the tire and a sealant.
