Abstract

In a pneumatic tire in which a tread surface of a land portion has a curved profile protruding outward in the tire radial direction, initial braking performance is improved. Provided is a pneumatic tire including a tread portion 2. The tread portion 2 includes a first land portion 11. The first land portion 11 includes an inner edge 11i, an outer edge 11o, and a tread surface 11s between the edges. The inner edge 11i is closer to a tire equator C than the outer edge 11o is. On the meridian cross-section including the tire rotation axis, the tread surface 11s has a curved profile 15 protruding outward in the tire radial direction when the tire 1 is in a normal state in which the tire 1 is mounted on a normal rim at a normal internal pressure under no load. The profile 15 includes an inner curved portion 16 on the inner edge 11i side and an outer curved portion 17 on the outer edge 11o side. A radius Ri of curvature of the inner curved portion 16 is greater than a radius Ro of curvature of the outer curved portion 17.
