To provide a pneumatic tire that ensures maneuvering stable performance, and properly exhibits an effect of reducing rolling resistance and improving wet braking performance.
Tread rubber 10 arranged outside a carcass layer 7 of a tread part 3, has a cap part 12 formed of nonconductive rubber and constituting a grounding surface, a base part 11 arranged inside in the tire radial direction of the cap part 12, and a conductive part 13 formed of conductive rubber and extending in the thickness direction TD of the tread rubber 10 from the grounding surface to a bottom surface of the tread rubber 10. A thickness of the conductive part 13 in a central part in the thickness direction TD of the tread rubber 10 is relatively large, while a thickness of the conductive part 13 in both end parts in the thickness direction TD of the tread rubber 10 is relatively small.
