The invention relates to vehicle tires with a profiled belt (2) comprising a groove (3) with groove walls (4) at which a groove expansion (7) that expands the groove (3) towards the tread surface (5) terminates and with a groove (3) width A of 0.4 mm to 1.2 mm. The trade-off between wetting properties, dry brakes, and rolling noise is improved in that the groove (3) is made of the following five sections (11, 12, 23) in the axial extension of the groove: • a respective edge section (12) which adjoins the respective delimiting circumferential groove (1) and has a first length (13), • an inner section (11) which is arranged axially between the edge sections (12) and has a second length (10) that is greater than the first length (13), and • a respective transition section (23) which is arranged between the inner section (11) and each of the two edge sections (12) and has a third length (24) that is shorter than or equal to the first length (13); the groove edges (6) run parallel to one another and have a constant first spacing B1 of 2.2 mm to 3.2 mm in each of the edge sections (12); the groove edges (6) run parallel to one another and have a constant second spacing B2 of 1.6 mm to 2.2 mm in the inner section (11); the first spacing B1 is greater than the second spacing B2 by 0.5 mm to 1.5 mm; and a third spacing B3 of the groove edges (6) increases from the second spacing B2 to the first spacing B1 in each of the two transition sections (23).
