Pneumatic vehicle tire, in particular a commercial vehicle tire, having a tread which has a profile and has at least one circumferential groove (1) which is encircling in the circumferential direction, is embodied to a profile depth (PT) and in the cross section, starting at the tread external face, is composed of three adjoining groove portions, one outer groove portion (2) that expands in a funnel-shaped manner toward the outside, one 1 mm to 3 mm wide contracted groove portion, and one inner groove portion (4) which lies radially inward, is expanded in relation to the contracted groove portion (3) and has the largest cross-sectional face of all portions, and which is delimited by two cover flanks (4a), lateral groove flanks (4′b, 4″b) that adjoin said cover flanks (4a), and a groove base (4c). The lateral groove flanks (4′b, 4″b) in the expanded groove portion (4), while reducing the mutual spacing thereof from the groove base (4c), run at an angle (γ) of 5° to 25° in relation to the radial direction and in the direction of the circumferential extent of said lateral groove flanks (4′b, 4″b) run in a wave form
