Abstract
A pneumatic tire includes a tread portion on each side of the equatorial plane. At least two circumferential main grooves and three land portions are formed in the tread portion. In a cross section in a meridian direction of the pneumatic tire, profile lines of the land portions form arcs, and an intersection of extension lines of profile lines of adjacent land portions forms an inflection point in a circumferential main groove. Tensile strength of a reinforcing layer in the land portions is larger than that in the circumferential main groove having the inflection points.
