Each of the plurality of blocks (5) has a plurality of sipes (6A, 6B, 6C, 6D) extending along the tilted grooves (4). The plurality of sipes at least include: at least one first sipe located on the tire equator side (6A); at least one second sipe (6B) located on the tread end side (Te); and at least one third sipe (6C) located between the first sipe (6A) and the second sipe (6B) in a tire axial direction. An end on the tread end side of the third sipe (6C) is located on an extension line of the second sipe (6B).",
