A block 100 includes a pair of extending portions 40 that respectively extend in the tire circumferential direction from a lateral surface 25A and a lateral surface 25B, and a pair of protruding portions 60 that respectively protrude from the pair of extending portions 40 in the tire circumferential direction. The extending portion includes an acute corner 45 formed by the inclined groove and the circumferential groove intersecting with each other. An extending portion 40A is positioned at one end side in the tread width direction, and an extending portion 40B is positioned at the other end side in the tread width direction. An outer surface of the protruding portion 60 in the tire radial direction is inclined relative to the tire radial direction. |
