The elevations (10) of the buffing indicator (9, 9?, 9?) are dome-shaped and have a circular base area with a diameter of 0.5 mm to 2.0 mm.

Abstract: A pneumatic vehicle tire, in particular a commercial-vehicle tire, having a one- or multi-ply carcass, a multi-ply belt or breaker and having a profiled tread with grooves formed to a profile depth, wherein the profiled tread is provided at the tire shoulders either with a respective block row (2) or with a respective profile rib (7), wherein the blocks (1) of the shoulder-side block rows (2), or the shoulder-side profile ribs (7) each have a peripheral edge (1a, 7a) laterally delimiting the ground contact patch of the tire, or a shoulder rounding with a radius of up to 30.0 mm, wherein shoulder flank surfaces that extend in a radial direction adjoin the peripheral edges or the shoulder roundings, and wherein, in the case of shoulder roundings, an imaginary section line is defined between an envelope of the tread that is continued beyond the shoulder rounding and the shoulder flank surface that is continued beyond the shoulder rounding.

Abstract: 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.

Abstract: Tread profile of a vehicle tire with profile elements (1,12,13,14,15,6) separated from one another by grooves (7,8,9,10,23), wherein the profile elements (13,14,1,12) separated by a groove (9,7) are outwardly delimited in the radial direction R by a radially outer surface (16) forming the ground contact area and toward the groove (9,7) respectively by a profile element flank forming a groove wall (17,18), wherein a rubber rib (20,19) extending in the extension direction of the groove (9,7) is respectively formed in the profile element flanks which delimit the groove (9,7) and each form a different groove wall (17,18) of the groove (9,7), wherein the rubber rib (19) formed in one groove wall (17) is formed in a different radial position of the vehicle tire than the rubber rib (20) formed in the other groove wall (18), wherein the two rubber ribs each (19,20) extend over the entire extension length of the profile element flank and wherein each of these two rubber ribs (19,20) respectively extends along its enti

Abstract: The invention relates to a pneumatic vehicle tire having a tread with profile block rows (1, 2) with profile blocks (5) delimited by channels (3, 4), which channels (3, 4) form T-shaped intersections in plan view and are delimited by a channel base (6, 6?) and by block flanks (5a, 5?a), wherein, in channels (3), there are formed projections (7, 7?) which, in a radial direction, have at their highest point a height (h1, h1?), in relation to the lowest point of the channels (3), of 10% to 80% of the profile depth. The projections (7, 7?) are positioned in intersection regions of T-shaped intersections of the channels (3, 4) and are attached to that block flank (5a) which is situated opposite the opening-in point of the opening-in channel (4).

Abstract: 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 (1) running in the central region of the tread with profile blocks (2) separated from one another by transverse grooves (3) and into shoulder-side profile ribs, wherein at least one of the circumferential grooves (4) adjoining a central profile rib (1) has, in cross section, a radially outer sipe-like narrow section (6) and a channel (8) adjoining this in the interior of the tread which is configured to be wider than the sipe-like narrow section (6) and which is delimited by two channel walls (8b) and a channel bottom (8a) forming the groove bottom, and wherein this circumferential groove (4) is interrupted in its course by entry points of transverse grooves (3). Opposite the entry points, a projection (9, 9?) is formed locally in each case on the channel wall (8b) located opposite the entry points of the transverse grooves (3).

Abstract: A pneumatic vehicle tire, in particular utility vehicle tire, having a tread which has a directional profiling with shoulder-side and middle profile ribs running in a circumferential direction, wherein at least one of the middle profile ribs (1), which is in particular a profile rib running along the tire equator, is traversed in an axial direction by sipes (4) with a width (b1) of 0.5 mm to 1.2 mm, each of which has a central portion (4a), in which the sipe (4) runs with an undulation in the direction of extent thereof, and two lateral portions (4b). The sipes (4) extend, in plan view, in an arc shape and symmetrically with respect to the centerline of the profile rib (1), and, in the lateral portions (4b) and in the central portion (4a), have a uniform undulation running in the radial direction, on which the undulation present in the extent direction of the sipes (4) is superposed only in the central portion (4a) of the sipe (4).
