Abstract
A pneumatic vehicle tire, in particular for heavy commercial trucks, having a tread with a number of circumferential grooves which run in the circumferential direction and which separate profile positives, such as block rows or profile ribs, from one another. The circumferential grooves are each bounded by a groove base and two groove edges. In order to effectively prevent the occurrence of tears at the groove base of the circumferential grooves, in particular at the groove base of the circumferential grooves which extend on the shoulder side, the groove base extends, viewed in cross section and in the axial direction, at an angle of inclination of 3 degrees to 15 degrees with respect to an envelope which encompasses the outer faces of the profile positives.
