Abstract:
Provided is a pneumatic tire ensuring conductivity while being reduced in weight, and having good fuel efficiency and handling stability. The tire includes a sidewall and a carcass, the sidewall including a laminate of two or more rubber layers including an inner sidewall layer (1) located closest to the carcass, and an outer sidewall layer (2) constituting an outer surface of the tire; the layer (1) including a rubber composition for (1); the layer (2) including a rubber composition for (2); the carcass including a carcass cord topped with a rubber composition for a carcass cord topping (3); the sidewall having a thickness of 3.0 mm or less; the layer (1) having a thickness of 0.2-1.0 mm; the composition for (1) having a volume resistivity of 5.0×107 Ω·cm or less; the compositions for (1) and for (2), and the compositions for (3) and for (1) satisfying specific relations.
