1. A pneumatic vehicle tire comprising a belt assembly having at least one belt ply which is reinforced with steel cords embedded in rubber material, each of the steel cords having the same number of steel filaments, in which the steel cords:
are arranged parallel to one another and at at least substantially equal distances apart within the at least one belt ply,
have rubber coating layers on both sides, the layer thicknesses of which in total are 0.10 mm to 2.00 mm,
when viewed in cross section are flattened open steel cords composed of four to six steel filaments periodically twisted together, at least two of which, when viewed in cross section, are flat-deformed,
have a first larger diameter and a second smaller diameter perpendicular thereto, the ratio of the first diameter to the second diameter is between 1.10 and 3.00,
are at equal distances from one another, which the equal distances are from 0.10 mm to 1.00 mm
wherein the steel filaments, when viewed in cross-section, are flat deformed in a random irregular manner to lack symmetry and uniformity within each filament and with respect to each other.
