The invention relates to a tread profile of a pneumatic vehicle tire having radially raised profile elements (4), which in a radial direction R of the tire are limited by a radial outer surface (6) forming the bottom contact surface, and having wave-shaped or zigzag-shaped sipes (7) having a zero line (8) of the wave shape or the zigzag shape, which zero line (8) forms the main direction of extension of the respective sipe in the radially outer surface (6), the greatest direction component of which zero line (8) is the axial direction A of the tire. Along the extension of the zero line (8), the wave shape, or zigzag shape, has peaks (9) and valleys (10) having amplitude a, which are formed in alternating sequence, wherein the sipes (7) at least along the wave-shaped or zigzag-shaped extension thereof are formed having a depth T1 measured in the radial direction R. In the region of extent of at least some, in particular all wave peaks (9) and/or at least some, in particular all wave valleys (10) of the sipe (7), one profile section each defined by the sipe (7), extending starting from the crest (maximum) of the wave peak (9), or from the low point (minimum) of the wave valley (10) in a direction that is vertical to the zero line (8) to the distance Li from the crest (maximum) of the wave peak (9) or the low point (minimum) of the wave valley (10), with L1 ≤ a, is formed as a recess (11) having a constant depth T2 - measured in the radial direction R - along the extension, starting from the radial outer surface (6), with T2 ≤T1(1/3).
