Pneumatic tire

A pneumatic tire comprising:

• a nonconductive carcass which runs into a bead portion from a tread portion via a side wall portion;
• a side wall rubber which is provided in an outer side of the carcass in the side wall portion;
• a rim strip rubber which is provided in an outer side of the carcass in the bead portion;
• and
• a conductive route which electrically connects a ground surface of the tread portion and a rim contact position of the bead portion,
• at least one of the side wall rubber and the rim strip rubber being formed by a nonconductive rubber,
• wherein a diametrical conductive portion extending in a tire diametrical direction in a tire meridian cross section is provided at least in a nonconductive position in a side rubber portion which is constructed by the side wall rubber and the rim strip rubber, the diametrical conductive portion is formed by a conductive rubber so as to construct a part of the conductive route,
• a conductive branch portion is provided so as to be branched from the diametrical conductive portion, extending at least in a thickness direction of the side rubber portion having a dimension in the thickness direction equal to or greater than 0.5 times an axial dimension of the side rubber portion, and is formed by a conductive rubber which has a different hardness from a rubber hardness of the side rubber portion, wherein the conductive branch portion is arranged in a plurality of rows in the tire diametrical direction,
• wherein the conductive branch portion is arranged in a plurality of rows in the tire diametrical direction.
