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 () or with a respective profile rib (), wherein the blocks () of the shoulder-side block rows (), or the shoulder-side profile ribs () each have a peripheral edge () 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. The shoulder flank surfaces are provided, at in particular regular intervals over the tire circumference and within a distance (a) of 1.25 times to 2.5 times the profile depth from the respective peripheral edge () or, in the case of shoulder roundings, from the imaginary section line, with at least one areal recess () having a depth (t) of 0.5 mm to 5.0 mm, which contains ribs () that extend parallel to one another and have a height (h) such that the ribs () do not project beyond the level of the shoulder flank surfaces.

Pneumatic vehicle tire

A pneumatic vehicle tire, in particular commercial vehicle tire, having a tread having in each case one shoulder-side profile rib () which is separated in each case from a central tread portion () by a wide circumferential groove () which is made to profile depth (T) and which runs around rectilinearly in the circumferential direction, wherein the circumferential groove () has a rounded groove base () and is delimited at the profile rib () by a rib flank (). Recesses () are formed on the rib flank () of the circumferential groove () at the profile rib periphery, which recesses have, in the direction of extent of the circumferential groove (), a length of extent () of 70% to 90% of the profile depth (T), at most of 30 mm, and in each case have, as seen in plan view, boundary surfaces () which run toward one another in an L shape and extend in the radial direction, and a bottom surface (), wherein, as seen in plan view, the one first boundary surface () runs into the profile rib () at an angle (&#x3b2;) of up to 35&#xb0; to the axial direction, and the second boundary surface () runs at an angle (&#x3b2;) of 90&#xb0; to 125&#xb0; to the first-mentioned boundary surface (), and wherein bottom surface () is situated at a depth (t) of 15% to 25% of the profile depth (T).

Pneumatic vehicle tyre

A pneumatic vehicle tire, in particular a commercial vehicle tire, having a tread with transverse grooves ('), which are continuous over the tread width and which, at least in sections, are formed to the profile depth and are the main grooves of the tread. Circumferential grooves () that run adjacent to one another in pairs and parallel to one another, at an angle (&#x3b1;) with respect to the circumferential direction of 10&#xb0; to 30&#xb0; and have a smaller depth than the profile depth divide the tread, with two sections () in each case between three transverse grooves (&#x2032;) following one another in the circumferential direction, into profile blocks (), wherein pairs of circumferential grooves following one another in the circumferential direction are offset with respect to one another in the axial direction, such that the circumferential grooves () of the pairs of circumferential grooves begin and end at substantially the same axial positions, wherein each circumferential groove () reaches, with a section () running beyond a transverse groove (), into a middle profile block () present between the circumferential grooves (), and wherein each circumferential groove () is formed shallower in at least one section () than in its other sections or its other section.
