Abstract: A pneumatic vehicle tire having a tread with profile blocks (4) formed by circumferential or diagonal grooves (1) and by transverse grooves (2), said profile blocks (4) each being provided with at least one sipe (5) that is straight or slightly curved in plan view, extends at least substantially parallel to the transverse grooves (2) and has a width of 0.3 mm to 2.0 mm, wherein the sipe (5) is bounded by two sipe walls (6), and wherein at least one protrusion (8) is provided on each of the otherwise unstructured sipe walls (6). The protrusion (8) formed on one sipe wall (6) is offset in the direction of extent of the sipe (5) with respect to the protrusion (8) formed on the other sipe wall (6), without a mutual overlap.

Abstract: A pneumatic vehicle tire having a profiled tread (1) that consists of an electrically nonconductive rubber material and has a central tread region (3) and, at each of the shoulders, a profile block row (2) having transverse grooves (7) that extend at an angle (?) of 70° to 90° to the circumferential direction, wherein the shoulder-side profile blocks (8) have block corners (8?) toward the tread center, wherein the central tread region (3) is subdivided into a multiplicity of profile blocks (4) and is provided with grooves (5) that extend at angles (?) of at most 60° to the circumferential direction, wherein all of the profile blocks (4, 8) are each provided with a number of sipes (9, 9?), and wherein the tread (1) is passed through in the radial direction by at least one electrically conductive rubber strip (14) extending in the circumferential direction, said rubber strip (14) forming an electrically conductive passage between the substructure of the tire and the tread outer surface.
