Provided is a pneumatic tire (1), in which a tread rubber (7), a side-wall rubber (8) and a breaker rubber (9) have an intrinsic volume resistivity of 1 X 108 O·cm or higher, and in which a clinch rubber (3) and a chafer rubber (2) have an intrinsic volume resistivity of 1 X 108 O·cm or lower. The pneumatic tire (1) comprises a first conductive layer (4) interposed between a carcass ply and the edge portion and the side wall portion of the breaker rubber (9), a second conductive layer (5) contacting the first conductive layer (4) and interposed between the tread rubber (7) and a carcass (10), and a pen rubber layer (6) continuing from the second conductive layer (5) to the surface of the tread portion. The pneumatic tire (1) has a structure, in which the first conductive layer (4), the second conductive layer (5) and the pen rubber layer (6) have an intrinsic volume resistivity of 1 X 108 O·cm or lower, and in which the carcass ply contains a conductive fibrous material having an intrinsic volume resistivity of 1 X 108 O·cm or lower and contacts the clinch portion, the chafer portion and the first conductive layer (4). |
