Abstract
A tread pattern of a pneumatic tire includes circumferential main grooves, a land portion defined by the circumferential main grooves in the lateral direction, and sipes at intervals in a circumferential direction, the sipes connecting the circumferential main grooves with each other. Each of the sipes has a peak-like shape protruding to a first side in the circumferential direction. When, in a profile cross-section of the tread portion taken along the lateral direction, an arc passing through two land portion edge points at which a tread surface of the land portion is connected with groove wall surfaces of the circumferential main grooves and having a center point positioned on the equator line is set to a standard profile line, a profile line formed by the tread surface of the land portion is a swelling profile line protruding outward of the standard profile line in a radial direction.
