Abstract
Provided is a pneumatic tire. A sipe includes, on each of a leading side edge and a trailing side edge, a chamfered portion and a non-chamfered region in which no other chamfered portion is present. A maximum depth of the chamfered portion is shallower than a maximum depth of the sipe, and a width of the sipe is substantially constant. In a cross-sectional view perpendicular to a lengthwise direction of the sipe, at least one chamfered portion has a profile line that projects outwards in the radial direction beyond a chamfer reference line connecting the end portions of the chamfered portion, and a cross-sectional area of a chamfered region that is surrounded by the profile line, the sipe, and a tread contact surface of a tread portion is smaller than a cross-sectional area of a reference region surrounded by the chamfer reference line, the sipe, and the tread contact surface.
