Abstract
A pneumatic tire includes a carcass layer, a belt layer, a tread rubber having a cap tread and an undertread, a pair of side wall rubbers, a pair of rim cushion rubbers, and a grounding tread that is exposed to a road contact surface of the tread rubber and that penetrates the cap tread and the undertread to contact the belt layer in an electrically conductive manner. The grounding tread includes a widened portion having a cross-sectional area that widens toward a contact surface with the belt layer at the contact portion with the belt layer. The widened portion of the grounding tread has a profile shape that bulges outward in a tire width direction.
