The invention relates to a pneumatic vehicle tyre having a tread with at least one, in particular straight, circumferential groove () which is formed at profile depth (T), is delimited by groove flanks () and a groove base () of U-shaped cross section, and has a width (B) which is ascertained at the tread periphery in the axial direction, wherein a number of projections (), which are arranged distributed over the circumference of the circumferential groove () and are situated opposite one another in pairs in the axial direction, is formed on the groove base (), possibly with connection to the groove flanks (), a groove path () of the circumferential groove (), which groove path reaches profile depth (T), has a constriction and is of symmetrical configuration with respect to a plane (E) which is spanned by the radial direction and a vertical to the centre line of the circumferential groove (), running between respective projections. In a tyre of this kind, the projections should be configured in a more expedient manner with respect to the water discharge capacity of the circumferential groove. This is achieved by way of the projections () ending at the groove flanks () or at the groove base () in the circumferential direction and running in such a way that the groove path () runs symmetrically with respect to a second plane (E), which is spanned by the centre line of the circumferential groove () and the radial direction, and is made up of two Venturi sections () which narrow in the manner of a funnel to form the constriction.

Pneumatic tyre for a vehicle

Pneumatic vehicle tire having a profiled tread (), side walls () and rounded tire shoulders, wherein, when the tire is mounted on a rim, the tread () has, in a first operating state with no load, a first contact surface and outside of the contact surface has profiled shoulder portions () extending in the direction of the side walls (). The shoulder portions () have blocks (), between which grooves () extending in the direction of the side walls () are provided and which are provided with sipes () and/or grooves extending in the direction of the side walls (), wherein, in at least one further operating state of the tire mounted on the rim, the tire has a further contact surface, which is wider than the first contact surface and at least partially includes the shoulder portions () and the profiling thereof.

Tire tread

A pneumatic vehicle tire includes a tread rubber that is divided into tread elements, such as tread bars or circumferential ribs, by circumferential grooves and transverse grooves. A groove flank of a circumferential groove facing away from an outer shoulder runs at a first angle of inclination relative to the radial direction, and a groove flank opposite the groove flank facing away from the outer shoulder includes two flank portions respectively running at a second angle of inclination and a third angle of inclination relative to the radial direction. The radially inner flank portion has elevations that form a ribbed structure.
