A pneumatic tire comprises a carcass and a sidewall rubber, wherein the sidewall rubber is formed by laminating two or more layers of rubbers including a sidewall outermost layer rubber at a tire outer surface and a sidewall inner layer rubber closer to a tire inner surface than the sidewall outermost layer rubber is, the sidewall inner layer rubber has a thickness of 0.1 mm to 1.2 mm, a mass ratio of an anti oxidant in the sidewall inner layer rubber is 1.2 mass% or more, a proportion of the mass ratio of the anti oxidant in the sidewall inner layer rubber to a mass ratio of an anti oxidant in the sidewall outermost layer rubber is 0.7 to 2.0, and E'/E' is more than 0.57 and less than 1.5.",
