A pneumatic tire including, on a tread surface, rib-like land portions partitioned by a plurality of main grooves and/or a plurality of block-like land portions partitioned by lug grooves extending in a tire width direction, wherein sipes or small holes are provided in the land portions, multiple protrusions are disposed having a height that is less than a depth of the sipes or small holes, and the multiple protrusions are disposed so as to form a shape wherein a flow path width increases at a flow path convergence point where flow paths formed in a mesh-like shape between the protrusions converge from at least three directions, and a ratio of an area of the multiple protrusions to an area of a block-like land portion is 0.5 or greater and 0.9 or less.
