Abstract

A pneumatic tire and pneumatic tire assembly are configured by a resin tire frame member. A sound-absorbing material is provided to an inner face of the tire frame member. The sound-absorbing material is capable of absorbing sound. The sound-absorbing material is thermally welded to the inner face of the tire frame member.

Claims

1. A pneumatic tire comprising:

a tire frame member that is made from a resin; and

a sound-absorbing material that is thermally welded to an inner face of the tire frame member and that is capable of absorbing sound.

2. The pneumatic tire of claim 1, wherein the sound-absorbing material comprises a blended resin material.

3. The pneumatic tire of claim 2, wherein:

the tire frame member is formed of a thermoplastic resin material; and

the resin material blended into the sound-absorbing material is formed of a thermoplastic resin material.

4. The pneumatic tire of claim 1, wherein:

the sound-absorbing material is configured by a spongiform porous structure containing bubbles; and

a bubble density of a thermal weld layer formed by thermally welding the tire frame member and the sound-absorbing material together is lower than a bubble density of the sound-absorbing material.

5. A pneumatic tire assembly comprising:

the pneumatic tire of claim 1; and

a wheel onto which the pneumatic tire is assembled.
