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.

The present invention relates to: a sealing gel having a Mooney viscosity (ML1+4 @ 100 C.) in the range from 100 MU to 170 MU, a sealing compound comprising inventive sealing gel, a process for producing this sealing compound, the use of sealing gels for improving viscoelastic properties in sealing compounds, and the use of sealing gel-containing sealing compounds for improving rolling resistance properties in tyres having sealing layers.

The tire comprises a carcass reinforcement which extends into sidewalls. The tire is also provided with a protection device that protects against external attack. The protection device comprises a plurality of raised elements of height H that are arranged in the circumferential direction. The tire is also constructed such that each raised element is formed of at least two parts which are at least partially disjointed from one another along a separation zone. The separation zone is oriented substantially in the circumferential direction. Each part is able to come into contact with another part of the same raised element when one of the parts comes into contact with an external obstacle.

Provided is a tire structure capable of being combined with a rim, and the tire structure includes an air tube, a core provided on the air tube, and a tire outer layer provided on the core, and the core includes a body part positioned above a transverse diameter of the air tube and a wing part positioned under the transverse diameter of the air tube, and a lower end of the wing part is placed under an upper surface of the rim.

Provided is a pneumatic tire of the present disclosure comprising a puncture prevention member bonded to at least a part of an inner surface of a tire body, and the puncture prevention member satisfies relational expressions:

S100MT+4.5 and Y/(MT)2, where M is a 100% modulus in MPa of a portion of the puncture prevention member in which the 100% modulus is lowest, T is a thickness in mm of the portion of the puncture prevention member, Y is an initial rigidity in N/mm during nail intruding, and S is a penetration strength in N of a portion of the puncture prevention member in which the penetration strength is highest.

A pneumatic tire comprises a puncture prevention member adhered to at least a part of an inner surface of a tire body, wherein the puncture prevention member includes one or more protective layers each of which includes: an internal pressure retention layer; and a protective material located on a tire outer surface side of the internal pressure retention layer in at least a part of an extending region of the internal pressure retention layer.

Provided is a pneumatic tire including an indicator made of a protrusion portion or a recess portion extending in a tire circumferential direction is formed on a tire inner surface. A sound absorbing member or a sealant layer is applied to the tire inner surface along the indicator.

Provided is a rubber composition for a sealant which can be vulcanized at low temperature and is suitable in a retentivity, an adhering property, followability and a fluidity and which is excellent in a sealing property, wherein the rubber composition is prepared by blending 100 parts by mass of a rubber component containing butyl rubber and/or EPDM, 2 to 10 parts by mass of zinc oxide, 1 to 5 parts by mass of a thiuram vulcanization accelerator, satisfying the thiuram vulcanization accelerator: the zinc oxide=1:1 to 1:3, and 150 parts by mass or more of liquid polybutene or a process oil.
