Abstract: A pneumatic tire of the present disclosure includes: a pair of main grooves, lateral grooves and longitudinal grooves, wherein a center land, repeats, in the tire circumferential direction, four center blocks, each of the four center blocks includes a recessed portion that is open to the main groove, the lateral groove or the longitudinal groove and has one end closed, when the recessed portions provided in the four center blocks are defined as first to fourth recessed portions, the first recessed portion and the second recessed portion extend in a direction inclined to one direction with respect to the tire equator line, and the third recessed portion and the fourth recessed portion extend in a direction inclined to another direction with respect to the tire equator line, and a groove width of each of the first to fourth recessed portions is 5.0 mm or more.

Abstract: Provided is a pneumatic tire. In shoulder regions of a tread portion, as shoulder blocks, inner blocks and outer blocks, which have outer edges in a tire lateral direction at different positions on a tread contact surface, are alternately disposed in a tire circumferential direction. In shoulder grooves disposed between the inner blocks and outer blocks adjacent to each other in the tire circumferential direction, groove bottom protrusions, which extend from a laterally inner side to a laterally outer side in the tire lateral direction along the shoulder grooves over the positions of the outer edges of the inner blocks, are provided. Broad width portions having a relatively broad protrusion width of the groove bottom protrusions are disposed on a laterally outer side in the tire lateral direction with respect to the outer edges of the inner blocks in a front view.
