Commercial vehicle tire of radial design with a tread with circumferential grooves formed to a profile depth, which divide the tread into at least two profile ribs () running in the central region of the tread with profile blocks () separated from one another by transverse grooves () and into shoulder-side profile ribs, wherein at least one of the circumferential grooves () adjoining a central profile rib () has, in cross section, a radially outer sipe-like narrow section () and a channel () adjoining this in the interior of the tread which is configured to be wider than the sipe-like narrow section () and which is delimited by two channel walls () and a channel bottom () forming the groove bottom, and wherein this circumferential groove () is interrupted in its course by entry points of transverse grooves (). Opposite the entry points, a projection (') is formed locally in each case on the channel wall () located opposite the entry points of the transverse grooves ().

Commercial vehicle tire

A pneumatic vehicle tire including a utility vehicle tire has a tread with profile positives which are separated from one another in a circumferential direction by transverse channels which extend continuously from the central region of the tread as far as the lateral tread edges, respectively. The transverse channels are main channels of the tread and, at least over the major part of the course thereof, have the maximum provided profile depth. The transverse channels are provided, on the respective channel base thereof, with a row of base elevations formed so as to be distributed over the entire course of the transverse channels. The base elevations are attached to the channel flanks of the transverse channels and are configured such that their rubber volume becomes smaller the closer to the tread edge they are disposed.

Pneumatic vehicle tire

The invention is directed to a pneumatic vehicle tire having a tread with profile positives which are separated from one another in a circumferential direction by transverse channels which extend continuously from the central region of the tread to the lateral tread edges and which are main channels of the tread and which, at least over the major part of the course thereof, have the maximum provided profile depth. The tread has, as profile positives, two rows of transverse ribs which are of encircling form in the circumferential direction and which are separated from one another by respective transverse channels. The tread is of directional configuration, wherein the transverse ribs of one row, and thus the transverse channels running between the transverse ribs, run, with respect to the axial direction, oppositely in relation to the transverse ribs and transverse channels of the other row.
