  • Publication number: 20220371384
    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).
