摘要:
A pneumatic tire including rib-like land portions partitioned by a plurality of main grooves extending in a tire circumferential direction and/or block-like land portions partitioned by the plurality of main grooves and a plurality of lug grooves intersecting the main grooves in a tread surface. A plurality of protrusions are provided on a surface of the land portions, and at least two types of the protrusions, having different surface areas, are provided. Moreover, at least a majority of the protrusions adjacent to a small protrusion having a relatively small surface area are large protrusions having a relatively large surface area.
