Abstract
A pneumatic tire includes a tread portion having a pair of central block rows arranged on both sides of a tire equator. Each of the central block rows includes a plurality of central blocks arranged in a circumferential direction of the tire. Each of the central blocks includes a ground contacting face with an axially inner block edge facing the tire equator. The inner block edge includes a first inclined edge and a second inclined edge inclined in an opposite direction to the first inclined edge so that the inner block edge protrudes toward the tire equator. The first inclined edge includes a first circular arc portion with a center located on the side of the tire equator.
