Provided is a pneumatic tire in which a sealant layer entirely exhibits sufficient sealing performance. The present invention relates to a pneumatic tire including a sealant layer located radially inside an innerliner, the sealant layer being formed by continuously and spirally applying a generally string-shaped sealant to the inner periphery of a tire in the tire width direction from one side to the other, the attachment start portion of the sealant being located tire-widthwise inward from the tire-widthwise end of the sealant layer.

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.

Provided is a stable and highly productive method for producing a pneumatic tire. The present invention relates to a method for producing a pneumatic tire, the method including: sequentially preparing a sealant by mixing raw materials including an organic peroxide using a twin screw kneading extruder; and sequentially applying the sealant to the inner periphery of a tire.

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.

A kit for repairing a tire, comprising, a first pressurized container including a first fluid and a second pressurized container including a second fluid. The first fluid comprises a first propellant and an emulsion comprising styrene butadiene rubber, a foaming agent, and an antioxidant. The second fluid comprises isopropyl alcohol and a second propellant.

A method for producing a tire filled with a (meth)acrylic hydrogel, the method comprises a) providing a mixture comprising at least one water-soluble (meth)acrylic compound, water and an initiator, and b) filling the mixture in a tire in which the mixture polymerizes to form the (meth)acrylic hydrogel. The tire filling material is suitable for producing flat proof tires, enables fast and controlled cure and is insensitive towards dosage errors. Moreover, the tire filling material is environmental friendly and cost effective.

The pneumatic tire 1 for a motorcycle comprises a tread portion 2 comprising a belt layer 7, an inner liner layer 9 made of air impermeable rubber and arranged radially inside the belt layer 7, and a sealant layer 10 attached to a radially inner surface (9a) of the inner liner layer 9. The sealant layer 10 comprises a crown portion 10A arranged at a center thereof in a tire axial direction and a pair of shoulder portions 10B arranged on both sides of the crown portion 10A in the tire axial direction. Viscosity 2 of the shoulder portions 10B is larger than viscosity 1 of the crown portion 10A.

The invention relates to a pneumatic vehicle tire having a sound absorber composed of foam which is adhesively attached, in the interior of the tire, to the inner surface situated opposite the tread, wherein the sound absorber adheres to a previously applied, self-sealing sealant which, at least immediately after its application, has a tackiness required for the adhesive attachment of the sound absorber. The sound absorber is made up of a multiplicity of individual geometric sound absorber bodies which are not connected to one another, in that each of the geometric sound absorber bodies adheres to the sealant, and in that each of the geometric sound absorber bodies has a diameter of 1 mm to 50 mm.

The invention is directed to a pneumatic vehicle tire which includes a foam sound absorber in its interior, adhesively attached to the inner surface opposite from the tread and extending in an annular manner over the circumference of the tire. The sound absorber adheres to a previously applied, self-sealing sealant which, at least immediately after its application, has a tackiness required for the adhesive attachment of the sound absorber. The sound absorber is made up of a plurality of annular component sound-absorber elements that extend in the circumferential direction. Two directly adjacently arranged annular component sound-absorber elements are spaced apart from one another in the axial direction by a clear distance.
