  "textContent": "A pneumatic tire has a tread rubber (10) formed by a nonconductive rubber and a side wall rubber (9) formed by the nonconductive rubber. An outer surface of the side wall rubber (9) is provided with a band-like diametrical conductive portion (12) which is formed by a conductive rubber and extends along a tire diametrical direction. An outer end (12a) of the diametrical conductive portion (12) is exposed to a ground-contacting surface (E) or is connected to a conductive rubber member which is exposed to the ground-contacting surface. An inner end (12b) of the diametrical conductive portion (12) is exposed to a rim contact region or is connected to a rim strip rubber (4) formed by the conductive rubber. A narrow groove (13) is formed by depressing an outer surface of the diametrical conductive portion (12) and extends in a tire diametrical direction in a side wall portion (2).",
