  "textContent": "The present invention relates to a pneumatic tire that may effectively discharge static electricity accumulated in a vehicle body while preventing separation between a conductive portion and a cap rubber in a tread portion. The pneumatic tire 1 comprises a tread rubber 2G comprising a cap portion 11 having a tread surface 2A, and an electrically conductive portion 12 having a first end exposed at the tread surface 2A and a second end connected with an electrically conductive tire element which is electronically communicated with a rim when the tire is mounted on the rim. The conductive portion 12 is formed of a strip wound body such that a rubber strip 14 is spirally wound. The rubber strip 14 comprises a wide strip 15 having an electrically conductive property, and a narrow strip 16 having a width smaller than a width of the wide strip 15 and disposed radially outward on the wide strip 15. The narrow strip 16 is made of the same rubber material as the cap portion 11 to which the narrow strip 16 is joined.",
