Title: PNEUMATIC VEHICLE TIRE
Abstract:
A pneumatic vehicle tire of radial type of construction, having a tread with at least one shoulder-side profile strip (1) which is delimited toward the inner side of the tread by a circumferential channel and in which there are formed transverse channels (5) which end within the profile strip (1), wherein the circumferential channel (3) is delimited by two channel flanks (7, 8) and by a channel base (9) running in a circumferential direction and has a marginal edge (3a) running along the profile strip (1). Transverse channels (5) with a first length of extent (l1) and transverse channels (6) with a second length of extent (l2) smaller than the first length of extent (l1) are provided, wherein the lengths of extent (l1, l2) are measured in an axial direction from the margin (L) of the ground contact patch, wherein at least one relatively short and at least one relatively long transverse channel (5, 6) successively alternate in the circumferential direction, wherein the marginal edge (3a) running along the profile strip (1) forms, together with the adjoining groove flank (7) in the profile strip (1), indentations (11) which are arranged in succession in the circumferential direction and which, in the circumferential direction, extend in each case substantially over the region between the relatively long transverse channels (5) that are adjacent in the circumferential direction, and wherein the marginal edge (3a) has its greatest axial excursion (a) into the profile strip (1) in each case in the region of the relatively short transverse channel (6) situated between the relatively long transverse channels (5), wherein the greatest axial excursion (a) amounts to 2 mm to 5 mm.
