A run-flat tire is provided with: a carcass layer mounted between a pair of bead portions; and a run-flat reinforcing layer having a crescent-shaped cross-section, provided on a side wall portion on an inner side of the carcass layer in a tire width direction, a band-like sound absorbing member that extends in a tire circumferential direction adhering to a region of a tire inner surface corresponding to a tread portion, wherein the band-like sound absorbing member is locally arranged in at least one shoulder region within the region corresponding to the tread portion.

A tire noise reduction device is applicable for a tire, and the tire including an tread, an inner surface, and a cavity defined inside the inner surface and configured to accommodate the tire cavity noise absorber. The tire cavity noise absorber contains at least one sound absorbing material, each of the at least one sound absorbing material includes an air chamber defined therein, a contacting face, and an extending face opposite to the contacting face. The contacting face is adhered on a portion of the inner surface corresponding to the tread by using adhesive material, and each sound absorbing material further includes a channel passing through the extending face, communicating with the air chamber, and facing a central direction of the tire.

The present application relates to a wheel with a sound absorber, the sound absorber being mounted in a wheel air chamber to reduce acoustic resonance, wherein the sound absorber is configured as a flat hexahedral box resonator and fastened to a wheel hub through a band, a first positioning mechanism is provided between the hub and the box resonator to fix the relative positions of the hub and the box resonator, and a second positioning mechanism is provided between the box resonator and the band to fix the relative positions of the box resonator and the band. According to the technical solution of the present disclosure, the resonator is positioned and fixed more reliably on the wheel, and the wheel is simple and economical in manufacturing, and convenient and controllable in installation and operation.

A tire having an adhesive sealant applied to the radial interior of the tire in the region of the belt reinforcements of the crown with a noise-dampening foam ring having circumferential grooves in the radial outside surface of the foam is applied to the adhesive sealant. The grooves of the foam are laterally aligned with the circumferential grooves of the tire such that the foam touches the sealant on areas that are not laterally aligned with the longitudinal grooves of the tire.

The invention relates to a pneumatic vehicle tire with at least one sound absorber adhesively attached in its interior to the inner surface opposite the tread. The invention further relates to a process for detecting a pneumatic vehicle tire with a sound absorber and to a process for recycling a pneumatic vehicle tire with a sound absorber.

According to the invention the radially inward-facing surface of the sound absorber has at least one colorant applied to it.
