The present invention is directed to a pneumatic tire comprising a tread portion, two bead portions, two sidewalls extending between the tread portion and the respective bead portions, an inner surface defining a tire cavity, a sealant material layer covering the inner surface radially below the tread portion within the tire cavity, and at least one noise dampening strip which is partially covering and attached to the sealant material on a radially inner side and along a circumferential direction of the sealant material layer. The sealant material layer has at least one plateau region supporting the noise dampening element and one or more bottom regions provided laterally beside the plateau region, and wherein the plateau region extends out of the bottom regions in a radially inner direction.

Proposed is a tire with self-generation and sound absorption and, more particularly, is a tire with self-generation and sound absorption that operates an electronic module through self-power generation and has improved sound absorption performance. The tire with self-generation and sound absorption includes: a wall structure formed on a surface of an inner liner of the tire; a sound absorber spaced apart upward from the inner liner with both ends coupled to the wall structure and blocking sound generated by surfaces of treads and a road surface; and an electronic unit disposed on the surface of the inner liner and positioned between the inner liner and the sound absorber.

The pneumatic tire of the present technology includes: a tread portion; sidewall portions; and bead portions. A pattern of grooves is formed on the tread portion, and a strip-shaped sound-absorbing member is bonded along the tire circumferential direction to a region of the tire inner surface corresponding to the tread portion via an adhesive layer. A first ground contact region is defined between the tire ground contact edge on one side in the tire width direction and the tire equatorial plane, and a second ground contact region is defined between the tire ground contact edge on the other side in the tire width direction and the tire equatorial plane. The sound-absorbing member is offset with respect to the tire width direction so that the centroid of a cross-section of the sound-absorbing member in a plane that includes a tire axis is located within the first ground contact region.

A pneumatic vehicle tire including at least one sound absorber adhesively attached to the inner surface opposite the tread in the interior of said tire, wherein the at least one sound absorber adheres to an adhesive, and to an adhesive composition for securing at least one sound absorber to a surface of a pneumatic vehicle tire. The adhesive includes 10% to 80% by weight of at least one rubber, 11% to 80% by weight of at least one polyolefin and 2% to 20% by weight of at least one hydrocarbon resin. The adhesive has optimized flow characteristics and an optimized stickiness.

An auxiliary air chamber member includes: a lower surface arranged on the outer circumferential surface side of a well section; an upper surface arranged outward from the lower surface; an auxiliary air chamber formed between the upper surface and the lower surface; a pair of edges that join the lower surface and the upper surface on both sides in the width direction and that engage with the well section; and a plurality of joining sections that partially join the upper surface and the lower surface as a result of being sunk into the interior of the auxiliary air chamber from the upper surface and the lower surface between one edge and the other edge along the wheel width direction Y. The joining points of the individual joining sections are arranged on the strong axis of the cross-sectional main axis of the auxiliary air chamber member in an axial right section.

A pneumatic tire comprises a tread portion extending in a tire circumferential direction and having an annular shape; a pair of sidewall portions disposed on opposite sides of the tread portion; and a pair of bead portions disposed toward the inside of the sidewall portions in a tire radial direction; wherein a sound absorbing member is fixed via an adhesive layer to an inner surface of the tread portion along the tire circumferential direction, and when a temperature t of the sound absorbing member is at least in a range from −20° C. to 80° C., an elongation at break y (%) and the temperature t of the sound absorbing member satisfy relationships y≥t+100 and y≤2t+440.

A vehicle tire-wheel assembly includes: a wheel main body; a Helmholtz resonator provided on an outer peripheral surface of a well portion of the wheel main body; a tire attached to an outer peripheral surface of the wheel main body so that the tire covers the Helmholtz resonator; and a separation restraining part which, in cooperation with the tire, restrains the Helmholtz resonator from separating from the outer peripheral surface of the well portion.
