Abstract
In an assembly of a pneumatic tire and a rim, in which a tire cavity is formed between the pneumatic tire and the rim by mounting the pneumatic tire on the rim, a noise suppressing body extending in a circumferential direction is disposed inside the tire cavity. The noise suppressing body includes a first sound absorbing material layer arranged apart from an inner surface of a tire tread part through a cavity and a second sound absorbing material layer disposed at the rim side of the first sound absorbing material layer and having lower air permeability than the first sound absorbing material layer.

An assembly of a pneumatic tire and a rim, comprising:
- a rim;
- a pneumatic tire mounted on the rim;
- a tire cavity formed between the pneumatic tire and the rim;
- and
- a noise suppressing body disposed inside the tire cavity and extending in a circumferential direction of the tire,
- wherein the noise suppressing body comprises (i) a first sound absorbing material layer spaced from an inner surface of a tread part of the pneumatic tire with a cavity therebetween, and (ii) a second sound absorbing material layer disposed at the rim side of the first sound absorbing material layer and having lower air permeability than the first sound absorbing material layer, and
- wherein the noise suppressing body has a gas layer between the first sound absorbing material layer and the second sound absorbing material layer.
An assembly of a pneumatic tire and a rim, comprising:
- a rim;
- a pneumatic tire mounted on the rim;
- a tire cavity formed between the pneumatic tire and the rim;
- and
- a noise suppressing body disposed inside the tire cavity and extending in a circumferential direction of the tire,
- wherein the noise suppressing body comprises (i) a first sound absorbing material layer spaced from an inner surface of a tread part of the pneumatic tire with a gas-filled cavity therebetween, and (ii) a second sound absorbing material layer disposed at the rim side of the first sound absorbing material layer and having lower air permeability than the first sound absorbing material layer,
- wherein the second sound absorbing material layer is formed of fiber structure materials or porous materials, and
- wherein the noise suppressing body has a third sound absorbing material layer disposed at the rim side of the second sound absorbing material layer and having lower air permeability than the second sound absorbing material layer.
