Abstract
A pneumatic tire includes chamfered portions respectively formed on a leading side edge and a trailing side edge of a sipe. The sipe includes a non-chamfered region in which other chamfered portions are not present, in a plan view of a tread portion. At least one of the chamfered portions includes an outer edge profile line not parallel to a ridge line of the sipe. When the chamfered portion including the outer edge profile line not parallel to the ridge line of the sipe is divided into an inner region and an outer region corresponding to half a chamfer length of the chamfered portion in a tire width direction, a projected area of the outer region positioned on a rib outer side is larger than a projected area of the inner region positioned on a rib inner side.
