Pneumatic vehicle tyres for utility vehicles which have profiled tread comprising two axially adjacent circumferential ribs (3,4) that are separated by a circumferential groove (8) of depth H, wherein the circumferential groove (8) is delimited in the axial direction A by two groove walls, wherein the circumferential ribs (3, 4) are outwardly delimited in the radial direction R by a radially outer surface forming the road contact surface, and wherein the circumferential groove (8) is formed from a radially inner extension section of height H1 and a radially outer extension section of height H2 which is radially adjacent to said inner extension section, wherein the circumferential groove (8) in the radially inner extension section is configured as a channel of height H1 and width B1 measured in the axial direction A, which channel extends over the circumference of the tyre, and comprising first (12) and second (13) circumferential regions arranged over the circumference in an alternating sequence in the radially outer extension section along the extension thereof in the circumferential direction U, wherein the radially outer extension section of the circumferential groove (8) is designed in the second circumferential regions (13) with a maximum width B3, where B3> B1, and in the first circumferential regions (12) is designed along the extension thereof in the circumferential direction U with a width B2, where B2< B1, wherein in the first circumferential regions (12) in the transition to the radially outer surface, each of the two flanks (15, 16) forming the groove walls are formed with a chamfer (17, 18) to the circumferential groove (3, 4) of height H4, where H4< H2, and are formed along the radial extension thereof in the radially outer extension section, from radially inside to radially outside to the chamfer (17, 18) at a spacing B2 from each other. |
