Provided is a pneumatic tire which achieves the improvement of the flexibility of setting of steering stability on a dry road surface and steering stability on a wet road surface while securing a conductive path and suppressing the deterioration of rolling resistance. Tread rubber (5) of a pneumatic tire includes tread rubber (5) that forms a ground contact surface. When the ground contact surface is divided into two parts: a mounting inner side (WD1) and a mounting outer side (WD2), the tread rubber (5) has an inner cap part (52) that forms an inner ground contact surface and is produced from non-conductive rubber, and an outer cap part (53) that forms an outer ground contact surface. The inner cap part (52) has a branched conductive part (54) that is formed from conductive rubber ranging from the ground contact surface of a mounting outer end (52a) of the inner cap part (52) to the side surface or bottom surface of a mounting inner end (52b) while branching off at a plurality of positions. The outer cap part (53) does not have branched conductive rubber. The branched conductive part (54) is formed from the conductive rubber with a rubber hardness different from that of the non-conductive rubber that forms the inner cap part (52). |
