A pneumatic vehicle tire with a tread comprising circumferential grooves () and at least one profile rib (), which runs around in the circumferential direction and formed in which there are grooves () which at a groove flank () of a circumferential groove () that delimits the profile rib () open into it, wherein the groove flanks () of the circumferential groove () run at an angle (β) of 12° to 17° to the radial direction, thereby widening the circumferential groove () in the direction of the periphery of the tread. The grooves () run at an angle (α) of 45°±20° to the axial direction, end within the profile rib (), have a maximum depth (t) of 3.5 mm and open in each case into a local indentation (), which is formed at the groove flank (), reaches up to the periphery of the tread, is concavely rounded along the groove flank () and has a bottom () that runs in particular parallel to the periphery of the tread and is at a distance (c), determined in the radial direction, of 0.5 mm to 2.0 mm from the deepest point of the groove () of the circumferential groove ().
