Abstract: A pneumatic tire comprises a first sound damper fixed to a tire inner surface and being made of a sponge material; a second sound damper disposed on a tire internal space side of the first sound damper, and being made of a sponge material; and a communication device retained between the first sound damper and the second sound damper. The second sound damper has a hardness in a range of greater than 25N and no greater than 55N. The first sound damper has a hardness in a range of no less than 25N and less than 55N. The hardness of the second sound damper is greater than the hardness of the first sound damper. The hardness is measured in accordance with the Method A in Section 6.4 of the test methods as defined under the Hardness Tests in Section 6 of JIS K6400-2 (2012).

Abstract: A pneumatic tire in accordance with the present disclosure comprises a first sound damper fixed to a tire inner surface and being made of a sponge material; a second sound damper disposed on a tire internal space side of the first sound damper, and being made of a sponge material; and a communication device retained between the first sound damper and the second sound damper, wherein the second sound damper has a hardness greater than a hardness of the first sound damper.

Abstract: A tire which includes a carcass which extends from a pair of bead portions through a sidewall portion to reach a tread portion and an inner liner disposed at an inner circumferential surface of a tire main body is provided. The tire further includes a sound control layer which covers at least a part of an inner circumferential surface of the tire. The inner liner includes an end in a tire width direction annularly extending in a tire circumferential direction on the inner circumferential surface of the tire main body. The sound control layer is fixed on the end in a tire width direction to cover at least a part of a periphery of the end in a tire width direction of the inner liner.

Abstract: A pneumatic tire in accordance with the present disclosure comprises a first sound damper fixed to a tire inner surface and being made of a sponge material; a second sound damper disposed on an inner-tire space side of the first sound damper, and being made of a sponge material; and a sensor retained to at least the first sound damper, the sensor being configured to detect a displacement of the tire inner surface or a physical quantity calculable based on the displacement of the tire inner surface, wherein the first sound damper has a hardness greater than a hardness of the second sound damper.

Abstract: A tire includes a pair of bead portions, a pair of sidewall portions arranged at an outer side in a tire radial direction of the bead portions and a tread portion arranged between the sidewall portions, and a reinforcing rubber layer is provided to the sidewall portions. The reinforcing rubber layer extends over at least a part of the tread portion from the sidewall portions. The tire further includes a sound control layer which covers at least a part of an inner circumferential surface of the tire. The sound control layer is not laminated on the reinforcing rubber layer.
