  "textContent": "Provided is a pneumatic tire capable of providing improved steering stability performance on dry road surfaces and improved steering stability performance on wet road surfaces in a compatible manner. A chamfered portion (A, B) and a non-chamfered portion (A, B) are provided in each of an edge (A) on a leading side and an edge (B) on a trailing side of a sipe (). In a meridian cross-sectional view, a profile line (PL) of a rib () projects further to an outer side in a tire radial direction than a reference tread profile line (PL). A radius of curvature TR (mm) of the reference tread profile line (PL) and a radius of curvature RR (mm) of the profile line (PL) satisfy a relationship of TR>RR. Only one of the chamfered portions (A, B) on the leading side and the trailing side is disposed so as to straddle a maximum projection position (P). A maximum projection amount D (mm) of the rib () with respect to the reference tread profile line (PL) and a maximum width (W) (mm) of the chamfered portion (A, B) satisfy a relationship of 0.05 mm",
