Abstract: A pneumatic vehicle Eire having a tread with at least one profile block row (2, 3) which is divided into a multiplicity of profile blocks (2a, 3a) by transverse channels (6, 7) having channel flanks (7a) which extend at an angle (?, ?) of up to 50° with respect to the axial direction, wherein transverse channels (6, 7) are provided, in each of which there is formed a base elevation (8, 8I) which locally reduces the depth (t1) of the transverse channel (6, 7) and which connects successive profile blocks (2a, 3a) in circumferential direction to one another, wherein the base elevation (8, 8I) has at least two base elevation parts (8a, 8b, 8c) of different height (hmax, a, hmax, bc). Centrally on each of the base elevation parts (8a, 8b, 8c), there is formed at least one groove (10, 11) which runs in the dire tion of extent of the transverse channel (6, 7) and which emerges from the base elevation part (8a, 8b, 8c) at least on one side.
