TYRE

A tyre (1) includes a tread portion (2) being provided with a middle land portion (6B), a shoulder land portion (7B), and a shoulder circumferential groove (4B) extending between the middle land portion (6B) and the shoulder land portion (7B). The middle land portion (6B) is provided with two or more full-opened middle sipes (12) that are inclined with respect to a tyre axial direction. The middle sipes (12) each have two opposite sipe-edge portions provided with chamfer portions. 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.
