Abstract: A pneumatic vehicle tire including a carcass, particularly a radial carcass, a tread, and a belt-like reinforcement formed of at least two cord plies radially superimposed one above the other. At least one of the plies has rubberized metallic cord elements, and the other suitably has non-metallic cord elements. The cord elements cross each other from ply to ply, and the width of at least one cord ply is approximately equal to the width of the tread. The metallic cord elements, which particularly are made of brass-plated steel wire, further comprise a core and a mantle of wire, with the mantle including several twisted individual wires of equal size. The metallic cord elements in the cord ply comprise a core of a single wire filament, and a mantle comprising at least three single wire filaments. The mantle wire filaments respectively have a part which radially engages the wire filament of the core.
