Abstract: A pneumatic vehicle tire for utility vehicles has a profiled tread having two circumferential ribs that are adjacent and are separated by a circumferential groove of depth H formed from radially inner and outer extension sections of height H1 and H2. The groove in the radially inner extension section is a channel of height H1 and breadth B1, and in the outer extension section is configured, along its circumferential extent, with an alternating sequence of first and second circumferential regions. The two flanks in the first regions are each configured, in the transition to the outer surface of the rib, with a chamfer of height H4 such that H4<H2, and are spaced by a distance B2 along their radial extent in the outer extension section from radially inward to radially outward as far as the chamfer.
