In each chamfer portion of each middle sipe (12), chamfer widths at both ends in a sipe longitudinal direction of the middle sipe (12) are larger than a chamfer width of a central portion in the sipe longitudinal direction of the middle sipe (12). The shoulder land portion (7B) is provided with two or more shoulder sipes (14) that are inclined in a same direction as the middle sipes (12) with respect to the axial direction.",
