A ground contact surface being applied with a normal load includes center blocks 9 adjacent at least in the tire circumferential direction. The center blocks 9 each include: a short edge 11 that faces the center main groove 3 and has a smaller length in the tire circumferential direction; and a long edge 12 that faces the center main groove 3 on the opposite side of the short edge 11.
