A tire (1) is provided with: a circumferential main groove (100) extending in a circumferential direction on a tread surface; first and second circumferential sub-grooves (210, 220) located on both sides in the tread width direction of the circumferential main groove (100) and extending in the circumferential direction; and first and second rib-shaped central land portions (310, 320) formed between the circumferential main groove (100) and the first and second circumferential sub-grooves (210, 220). The first and second central land portions (310, 320) respectively have a plurality of width direction sipes (311, 321), the respective width direction sipes (311, 321) extend to the circumferential main groove (100) and form openings (312, 322), the circumferential main groove (100) has a shallow groove portion (110), and a deep groove portion (120) having a larger depth from the tread surface than the shallow groove portion, and the depth (D1) from the tread surface of the shallow groove portion (110) is smaller than the depth from the tread surface of the first and second circumferential sub-grooves (210, 220). |
