The first land portion is provided with sipes each extending from the first edge to the second edge. The sipes include bent sipes each including two or more sipe elements joined with each other to form a bent portion. The bent sipes include first sipes and second sipes. Each first sipe, as the sipes elements, includes at least one first sipe element inclined in a first direction with respect to a tyre axial direction and at least one second sipe element inclined in a second direction opposite to the first direction with respect to the tyre axial direction. All sipe elements of each second sipe are inclined in the first direction with respect to the tyre axial direction.
