The invention relates to a vehicle tire having a profiled tread with at least one profiled belt (2), in particular a circumferential rib (2) or a profiled block row, which is delimited by two circumferential grooves (1) and which has at least one groove (3) that connects the two circumferential grooves (1), said groove having a width B of 0.4 to 1.2 mm, wherein the groove (3) has a vertical channel (20) and a horizontal channel (18) in the form of local expansions, and the vertical channel (20) runs from an opening (9) of the tread surface (5) radially inwards so as to lead into the horizontal channel (18) and is connected to the two circumferential grooves (1) via the horizontal channel. The wetting properties are further improved in that the vertical channel (20) has a diameter D which decreases radially inwards at least in some sections, said diameter D being the largest diameter of a circle (10) which can be inscribed into a vertical channel (20) cross-sectional surface F oriented perpendicularly to the radial direction rR.
