Abstract

A pneumatic tire includes a plate-like member which is attached to a tread portion inner surface by at least two attaching portions arranged with a space in a tire circumferential direction, and has a space with respect to the tread portion inner surface between the two adjacent attaching portions, wherein a through hole penetrating toward the space is formed in the plate-like member, and wherein a support member capable of supporting the plate-like member is arranged in the space.

Claims

1. A pneumatic tire comprising a plate-like member which is attached to a tread portion inner surface by at least two attaching portions spaced apart in a tire circumferential direction, and has a space with respect to the tread portion inner surface between the at least two adjacent attaching portions,

wherein a through hole penetrating toward the space is formed in the plate-like member, and

wherein a support member capable of supporting the plate-like member is arranged in the space, and

wherein the support member is formed into a tubular shape which extends along a tire width direction.

2. The pneumatic tire according to claim 1, wherein the support member is formed by a porous material.

3. The pneumatic tire according to claim 1, wherein the support member is pinched by the plate-like member and the tread portion inner surface.

4. The pneumatic tire according to claim 1, wherein a plurality of the plate-like members are arranged at even intervals in the tire circumferential direction.
