The invention relates to a pneumatic vehicle tire comprising a profiled tread with at least one circumferential groove (1) which runs in a straight manner in the circumferential direction in plan view and which comprises a groove base (3) and two groove flanks (4). The groove base (3) is equipped with protrusions (5) which are distributed over the circumference of the tread and which function as sound absorbers, wherein each protrusion (5) has a first plane of symmetry (E1) which runs in the direction of extension of the circumferential groove (1) in plan view and a second plane of symmetry (E2) which runs perpendicularly to the first plane of symmetry (E1) in plan view, and each protrusion (5) is composed of a central protrusion part (6) formed centrally in the circumferential groove (1) and two lateral protrusion parts (7) facing the groove flanks (4). The central protrusion part (6) has, when viewed in plan view, an oval shape which is elongated in the direction of extension of the first plane of symmetry (E1), in particular an elliptical shape which is elongated in the direction of extension of the first plane of symmetry (E1), and is designed in the form of a section of an ovoid, in particular an ellipsoid, which is centrally flattened in the radial direction. Each of the lateral protrusion parts (7) has a smaller volume than the central protrusion part (6), is nose-shaped, and has a nose bridge which descends starting from the central protrusion part (6).
