Pneumatic tyres for a vehicle

Tread profile with a profile block row (1), wherein the profile block elements (4) are limited in the radial direction R of the tire toward the outside by a radially outer surface (6) forming the ground contact surface and in the axial direction A toward the respectively adjacent circumferential groove (2) by a profile block element flank forming a groove wall (10) of the circumferential groove (2), wherein in the radially outer surface (6) of profile block elements (4) of the profile block row (1) a group (7) of parallel fine cuts (11,12,13,14,15) arranged one behind the other in the circumferential direction is formed in each case, which extends starting from one circumferential groove (2) over a length L measured in the radially outer surface (6) and with a depth t1 and ends there, wherein these fine cuts arranged one behind the other in the circumferential direction U in the profile block element (4) of the length L with L≥6mm in the radially outer surface consist of a first (8) and a second (9) extension section, wherein in the first extension section (8) of the length b with b≤2mm adjoining the groove wall (10) of the circumferential groove (2) they extend along the groove wall (10) in each case to a depth t2 and in the second extension section (9) adjoining the first extension section (8) in the radially outer surface (6) with a depth t1 with (4 t1) ≤ t2 is formed, and wherein these fine cuts of the group (7) arranged one behind the other in a rotation direction D of the tire in a profile block element (4) are formed from one fine cut in this rotation direction D respectively toward the next fine cut with both an increasing depth t1 and an increasing depth t2.
