A pneumatic tire has a carcass ply, a tread rubber, a side wall rubber and a rim strip rubber. A topping rubber of the carcass ply and the side wall rubber are formed by a non-conductive rubber. The rim strip rubber is formed by a conductive rubber. A height of an outer end of the rim strip rubber is equal to or more than 50% of a tire cross section height. JIS A hardness of the side wall rubber is equal to or more than 59 degrees. A side conductive layer formed by the conductive rubber is provided between the side wall rubber and the carcass ply. The side conductive layer is connected to the tread rubber and the rim strip rubber. A conductive route reaching the outer end of the side conductive layer from a ground-contacting surface is constructed in the tread rubber.
