A pneumatic tire which comprises a land portion (10) and a land portion (20). A main groove (50) extending along the tire circumferential direction is formed between the land portion (10) and the land portion (20). The land portion (10) comprises a groove wall (10a) that forms the main groove (50). The land portion (20) comprises a groove wall (20a) that forms the main groove (50). The groove wall (10a) and the groove wall (20a) are serpentine along the tire circumferential direction (R) when seen from a plane of the tread surface, and the groove width of the main groove (50) in the tread width direction (WTR) varies in a predetermined repetition interval (λ) along the tire circumferential direction. The ratio of the minimum width (WMIN) of the groove to the maximum width (WMAX) of the groove satisfies a relation of 35%≦WMIN/WMAX≦85%.
