Abstract
Provided is a pneumatic tire. A chamfered portion and a non-chamfered portion are provided in each of an edge on a leading side and an edge on a trailing side of a sipe. In a meridian cross-sectional view, a profile line of a rib projects further to an outer side in a tire radial direction than a reference tread profile line. A radius of curvature TR of the reference tread profile line and a radius of curvature RR of the profile line satisfy TR>RR. Only one of the chamfered portions on the leading side and the trailing side is disposed so as to straddle a maximum projection position. A maximum projection amount D of the rib with respect to the reference tread profile line and a maximum width W of the chamfered portion satisfy 0.05 mm<W×D<1.50 mm.
