Abstract:
A pneumatic tire includes a tread portion provided with a pair of central blocks arranged on both sides of a tire equator. Each of the central blocks includes a ground contacting face having an axially inner block edge facing the tire equator. The inner block edge extends in a V-shaped manner including a first inclined edge and a second inclined edge inclined in an opposite direction to the first inclined edge. The second inclined edge has a circumferential length shorter than a circumferential length of the first inclined edge. Each of the central blocks includes a first portion having the first inclined edge and a second portion having the second inclined edge. The second portion of the central block includes an end wall at an opposite side to the first portion. The end wall includes a stepwise wall extending in steps toward a groove bottom.
