Abstract: A commercial vehicle tire of a radial type of construction with a cross-sectional height of 135 mm to 200 mm, a load index of 121 to 154, a radial-ply casing with at least one casing ply composed of steel cords embedded in rubber and with bead regions with bead cores and bead fillers around which the casing ply runs so as to form turn-ups. The casing ply is reinforced with steel cords of the construction 1+6, wherein the core filament (1) has a diameter (d1) of 0.19 mm to 0.22 mm and the ply filaments (2) have coinciding diameters (d2) of 0.17 mm to 0.20 mm, wherein the diameter (d2) of the ply filaments (2) is less than the diameter (d1) of the core filament (1) by at least 0.01 mm and wherein, at the crown of the tire, the steel cords are arranged in the casing ply with 60 epdm to 75 epdm.
