PROBLEM TO BE SOLVED: To provide a pneumatic tire having siping and capable of enhancing removal property of a knife blade while retaining an excellent three-dimensional shape. SOLUTION: The siping 7 has a zig-zag-like part 7a between length directions from one end E1 to the other end E2 at an opening edge shape opened at a block surface 5S and includes first, second and third displacement parts 11, 12, 13 extending in a depth direction from the block surface 5S while the zig-zag-like part 7a is displaced to the one and the other in the length direction while substantially retaining the opening edge shape. First, second and third displacement pitchα1 (=a1/h1),α2 (=a2/h2) andα3 (=a3/h3) obtained by dividing first, second and third respective displacement length a1, a2 and a3 by respective length h1, h2 and h3 in a tire radial direction satisfyα1>α2>α3.
