Abstract

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.
