A pneumatic tire includes at least one sound absorbing member having a band-like shape. The sound absorbing member is bonded to an inner surface of a tread portion along a tire circumferential direction. A correction body for correcting weight unbalance is fixed to a tire inner surface in a range corresponding to a light point of an entire tire including the sound absorbing member.

Provided is an attaching device and a method for attaching a band-like member to a tire inner surface. A holder that holds the band-like member in a wound state and a paddle are disposed in an inner portion of a tire, and a dispensed portion is pressure-bonded to the inner surface by repeatedly performing: a bonding operation in which a predetermined length dispensed from the band-like member in a wound state toward the inner surface is pressed, by moving the paddle close to the inner surface with no relative rotation of the tire in the circumferential direction with respect to the holder, and is pressure-bonded to the inner surface and a dispensing operation in which, after the bonding operation, the paddle is moved away from the inner surface, and together with relatively rotating the tire in the circumferential direction, a new dispensed portion is formed.

Disclosed is a tire configured for reducing noise during running of the tire by forming a predetermined shape in a groove of the tire to reduce a peak of air column resonance sound. The tire with reduced noise includes a first protrusion formed on a sidewall of a groove, protruding in a depth direction of the groove, and dispersing sound waves generated in a tread, and a second protrusion formed on the sidewall of the groove, protruding in a longitudinal direction of the groove, and dispersing sound waves generated in the tread.

A pneumatic vehicle tire (1) having a profiled tread (2) that merges at either side into sidewalls (3), the end of which is formed by a tire bead (5, 6) insertable in an airtight manner into a wheel rim (7) of a vehicle wheel (8), wherein an absorber (10) has been integrated into the pneumatic vehicle tire (1) for sound absorption and the cohesive bond consists of an adhesion promoter (11) applied between the absorber (10) and the inner surface (9) of the pneumatic vehicle tire (1), has been further developed in accordance with the invention in that the inner surface (9) of the pneumatic vehicle tire (1) has mutually alternating adhesion promoter sections (12) and adhesion promoter-free sections (13), the adhesion promoter-free sections (13) having been coated with a separating agent (14).

A 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 pneumatic tire further includes s a tread portion and each resonator faces the tread portion, the tread portion includes at least one circumferential longitudinal groove, and the opening is provided to penetrate a circumferential longitudinal groove of the tread portion.

Provided is a pneumatic tire having 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 applying a sealant to the inner periphery of a tire from which mold release agents have been removed.

To provide a pneumatic tyre without decrease in noise reduction effect during running.

[Solution ] It is a pneumatic tyre 1. The pneumatic tyre 1 has a noise damper 20 fixed to a tyre inner cavity surface 16 and made of a porous material. In the noise damper 20, a ratio (E2/E1) between breaking energy E2 after thermal aging performed by leaving the noise damper for 1000 hours under an environment of 80 degrees Celsius and breaking energy E1 before the thermal aging is 0.7 or more.

A pneumatic tire includes: an annular-shaped tread portion extending in a tire circumferential direction; a pair of sidewall portions disposed on both sides of the tread portion; and a pair of bead portions disposed on an inner side in a tire radial direction of the sidewall portions; and a band-like sound absorbing member being adhered on an inner surface of the tread portion in the tire circumferential direction; wherein the band-like sound absorbing member has a plurality of cuts, and both terminals of the cuts terminate at an inner side of the band-like sound absorbing member.

A pneumatic tire includes a planar-shaped receiver coil in a cavity region, and configured to receive a magnetic field through a carcass ply layer and generate a signal, and an element to receive power converted from the signal. A receiving region of the receiver coil is interposed between an outermost side of a bead core in the radial direction and an innermost side of a belt layer in the radial direction, and the receiving region faces in the width direction. When a maximum dimension of the receiving region along the radial direction of the receiver coil is a length D1, a distance from the receiving region to a nearest portion of the bead core to the receiving region is L1, and a distance from the receiving region to a nearest portion of the belt layer to the receiving region is L2, relationships L1>(D1/4) and L2>(D2/4) are satisfied.

A noise damper includes an open cell foam having a circumferential first tier and an interposed circumferential second tier including blocks and voids. The first tier has a radial height that is 3.0-8.0% of a section height and a first axial width. The second tier has a radial height that is 3.0-12.0% of a section height and a second axial width. The blocks span 10-30% of the second tier's inner circumference and the voids span 70-90% of the second tier's inner circumference.
