1. A pneumatic vehicle tire comprising a tread with at least one profile block row which is divided into a multiplicity of profile blocks by transverse channels having channel flanks which extend at an angle of up to 50° with respect to an axial direction, wherein the transverse channels are provided, in each of which there is formed a base elevation which locally reduces a depth (t1) of the transverse channels and which connects successive profile blocks in a circumferential direction to one another,
wherein the base elevation includes first, second, and third base elevation parts arranged adjacently to each other in the direction of extent of the transverse channel, such that the second base elevation part is in between the first and third base elevation parts,
wherein an upper surface of the second base elevation part is at a greater height than an upper surface of the first base elevation part, and wherein the upper surface of the second base elevation part is at a greater height than an upper surface of the third base elevation part,
wherein the upper surface of the first base elevation part is separated from the second base elevation part by a first depression, and the upper surface of the third base elevation part is separated from the second base elevation part by a second depression,
wherein the first base elevation part includes a groove that is formed centrally in its upper surface and which extends in the direction of extent of the transverse channel across the entirety of the upper surface of the first base elevation part to emerge from both sides of the first base elevation part,
wherein the third base elevation part includes a groove that is formed centrally in its upper surface and which extends in the direction of extent of the transverse channel across the entirety of the upper surface of the third base elevation part to emerge from both sides of the third base elevation part, and
wherein the second base elevation part includes a first groove that is formed centrally in its upper surface and which extends in the direction of extent of the transverse channel across only a first portion of the upper surface of the second base elevation part to emerge from only a first side of the second base elevation part, wherein the second base elevation part further includes a second groove that is separated from the first groove by the upper surface, the second groove being formed centrally in the upper surface of the second base elevation part and which extends in the direction of extent of the transverse channel across only a second portion of the upper surface of the second base elevation part to emerge from only a second side of the second base elevation part that is opposite the first side.
