To enhance cornering performance on each road surface and improve steering stability while ensuring traction performance and breaking performance of a pneumatic tire on a snow road or off-road. A shoulder land row (31) between a main groove (11) extending in the tire peripheral direction of a tread unit (2) and a tread end (TE) is partitioned into plan-view trapezoidal blocks (31B) with their widths reducing toward the outer side of a tire width direction by shoulder lug grooves (26) in an almost tire width direction. A plan-view trapezoidal notch (40) with its width reducing toward the inside of a block (31B) is formed in almost the center of the main groove (11) side edge of a block (31B), and an inclined surface (41) extending from the surface of the block (31B) toward the bottom of the main groove (11) is formed in the notch (40) integrally with the block (31B). This inclined surface (41) is formed stepwise by a plurality of recessed curved surfaces and protruding ridges formed between them. |
