PROBLEM TO BE SOLVED: To provide a pneumatic tire in which a conductive rubber for forming a conductive path in a tire side part is reduced, whereby a reduction effect of a rolling resistance can be enhanced.SOLUTION: A carcass ply 4 has a junction part 40X in which ends of ply materials 40 are confronted or laminated with each other. The junction part 40X is provided with a conductive tape 41 which is interposed between the ends of the ply materials 40 and is exposed on a surface of the carcass ply 4. A topping rubber of the carcass ply 4 is formed of a non-conductive rubber. A conductive path 50, which extends from a ground plane P1, which can contact a road surface, to the conductive tape 41 is formed in a tread part 3. An inner liner rubber 4a is formed of a conductive rubber and constitutes a conductive path which extends from an outside surface P2 of a bead part 1, which can contact a rim, to the conductive tape 41 which is exposed on a tire internal surface of the carcass ply 4. |
