Abstract
A pneumatic vehicle tire having bead portions that can be turned in is provided. Embedded in the bead portions are bead cores built up from load-carrying elements that essentially extend in a circumferential direction. The load-carrying elements are disposed in such a way that each element is in contact with at least two other load-carrying elements. The load-carrying elements, at least to the extent that they are coated with rubber, have a surface that prevents adhesion to vulcanized rubber. The load-carrying elements of a bead core are disposed in layers, with the elements of the outer layer being disposed in such a way that they do not contact one another.
