Abstract
A pneumatic tire is equipped with at least a tread part, a sidewall part, a bead part, and a carcass extending from tread part through sidewall part to bead part, and provided with a breaker part on the outside of carcass in the radial direction of the tire. The volume resistivity of each of a tread rubber, a sidewall rubber, a breaker rubber, and a carcass rubber formed in the tread part, the sidewall part, the breaker part, and the carcass respectively is set to 1×10Ω·cm or more. A conductive layer having volume resistivity of 1×10Ω·cm or less is provided between a carcass ply constituting the carcass and the sidewall rubber and has an exposed part to the tire surface. A rubber cement layer contacting with at least a part of the exposed part of the conductive layer and at least a part of the region that becomes a grounding surface in the tread part to the road surface is provided.
