Provided is a self-sealing tire that is excellent in the effect of reducing adhesion of foreign materials to the sealant layer, sealing performance, and road noise-reducing properties while maintaining the balance between them. The present invention relates to a pneumatic tire, including: a sealant layer located radially inside an innerliner; and a sound-absorbing layer located radially inside the sealant layer, the sound-absorbing layer being formed by applying a porous sound-absorbing material to the inner periphery of the sealant layer.

Provided is a pneumatic tire including: a sealant layer located radially inside an innerliner; and a sound-absorbing layer located radially inside the sealant layer, the sealant layer being formed of a generally string-shaped sealant provided continuously and spirally along the inner periphery of the tire, the sound-absorbing layer being attached with the sealant.

A self-repairing inflatable article including an inflatable component that includes an interior surface and an exterior surface, a sealed flexible package adjacent to the inflatable component, and a sealant composition disposed in the sealed flexible package. The sealed flexible package is configured to release the sealant composition upon puncture, tearing or other breach of the inflatable component.

Provided is a pneumatic tire with excellent tire noise-reducing properties. The pneumatic tire includes a resonator attached to the inner periphery of the tire, the resonator including a tube with an opening, and a cavity connected to the tube.

The present disclosure describes a self-repairing article comprising an inflatable component comprising one or more material layers wherein at least one material layer comprises an elastomer. It also describes a self-repairing article comprising a sealed flexible package disposed within or between material layers of the inflatable component, and a repair composition disposed in the sealed flexible package, wherein the sealed flexible package comprises a metal foil and is configured to release the repair composition upon puncture of the inflatable component.

A pneumatic vehicle tire is provided. The tire includes a thread, an inner surface lying opposite the thread, a self-sealing sealant and a sound-absorbing open-cell foam ring arranged inside the pneumatic vehicle tire. The foam ring is adhesively attached to the inner surface and adheres to the self-sealing sealant which is applied before the sound-absorbing open-cell foam ring is attached to the inner surface. The self-sealing sealant has, at least immediately after being applied, a tackiness required for an adhesive attachment of the sound-absorbing open-cell foam ring. A closed-cell material ring is arranged between the sound-absorbing foam ring and the self-sealing sealant to prevent a diffusion of the sealant into the open-cell foam ring. The closed-cell material ring effects an airtight condition.

A pneumatic vehicle tire which includes a sealant layer at least on the inner surface opposite the tread. The sealant layer has a radially inward-facing surface running in the axial direction substantially parallel to the belt package. Also provided is a process for detecting a pneumatic vehicle tire with a sealant layer and to a process for recycling a pneumatic vehicle tire with sealant. The sealant layer has at least one luminescent agent on its radially inward-facing surface. The tire is detected via the luminescent agent.
