PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of exhibiting excellent steering stability and riding comfort while ensuring rigidity of a tire side portion, while achieving electric conductivity.SOLUTION: Topping rubber of a carcass ply 7 and side wall rubber 9 are formed of non-conductive rubber, and rim strip rubber 4 is formed by conductive rubber. A height H4o of an outer end 4o of the rim strip rubber 4 is 50% or more of a tire cross section height TH based on a bead base line BL. JIS A hardness of the side wall rubber 9 is 59° or more. A side conductive layer 14 which has a thickness smaller than a thickness of the side wall rubber 9 and is formed of conductive rubber is provided between the side wall rubber 9 and the carcass ply 7. The outer end 14o is connected to tread rubber 10. The inner end 14i is connected to the rim strip rubber 4. In the tread rubber 10, a conductive path is formed from a ground-contact surface to the outer end 14o of the side conductive layer 14. |
