The invention relates to a pneumatic vehicle tyre comprising a directional tread having at least one row of tread blocks (1) with tread blocks (3) which are separated from one another by transverse grooves (4) and which have an incoming block edge (6a), that enters the underlying surface first as the tyre rolls during forward travel (R), and an outgoing block edge (6b) on each of the adjacent transverse grooves (4), each transverse groove (4) having groove walls (4a, 4b) extending from the block edges (6a, 6b), and transverse grooves (4) being provided in each of which at least one base raised portion (7) is formed which reaches up to both groove walls (4a, 4b) and which is delimited in the radial direction by a cover surface (8) that is inclined at an acute angle (δ) relative to the periphery of the tread in the cross-section of the transverse groove (4). The cover surface (8) of the base raised portion (7) is inclined relative to the periphery of the tread in such a way that the transverse groove (4) has, in the region of the cover surface (8), a depth (tG) determined in the radial direction that increases continuously from the groove wall (4a) extending from the incoming block edge (6a) to the groove wall (4b) extending from the outgoing block edge (6b).
