A pneumatic tire includes, in a tread surface, at least one circumferential groove extending along a tire circumferential direction and a plurality of widthwise grooves opening to the circumferential groove, the widthwise grooves having a groove width wider than a groove width of the circumferential groove at least in a portion opening to the circumferential groove, and the widthwise grooves extending in a direction inclined with respect to the tire circumferential direction. A recess is formed on a groove wall surface of the circumferential groove opposite to the widthwise groove. A wall surface defined by the recess includes an inclined surface inclined towards the widthwise groove from a tire radial direction outer side towards a tire radial direction inner side and a curved surface connecting a tire radial direction inner end of the inclined surface to a bottom defined by the recess, the curved surface having a center of curvature on the side of the widthwise groove. As a connection point between the inclined surface and the curved surface is at a position in the tire circumferential direction at which a width W of the recess in the tire width direction is smaller, the connection point is located further inward in the tire radial direction. |
