The present invention provides a pneumatic tire having superior electrical conductivity, fuel efficiency, steering stability and crack growth resistance. The present invention is a pneumatic tire having a specific structure and provided with: a sidewall section comprising two or more laminated layers of rubber that include an outer sidewall layer (1) forming an outer tire surface and an inner sidewall conductive layer (2) that is connected to a clinch and a breaker and is disposed between a carcass and the outer sidewall layer (1); a tread section; a bead section provided with the clinch; the carcass; the breaker; and a conductive rubber, wherein the thickness ratio of the outer sidewall layer (1) to the inner sidewall conductive layer (2) in the sidewall section, and the ratio of the storage elastic modulus E'(1) of the outer sidewall layer (1) at 70°C to the storage elastic modulus E'(2) of the inner sidewall conductive layer (2) at 70°C in the sidewall section, are respectively within specific ranges, and the volume resistivity of the inner sidewall conductive layer (2) is within a specific range. |
