Pneumatic vehicle tire for utility vehicles

Abstract

The invention relates to a pneumatic utility vehicle tire of a radial type of construction, in particular for trucks, buses, and truck trailers, which has a four-ply or multi-ply belt (4) comprising a barrier ply (5), two working plies (6, 8) and a 0° ply (7), wherein steel cords (10) are arranged in the 0° ply (7), comprising at least two strands (11) each with at least 6 steel filaments (12), and wherein twisting causes each strand to have an identical first twist angle α and the steel cord to have a second twist angle β. The invention is distinguished in that the steel cord (10) of the 0° ply (7) has the construction 2 to 4×n×d, with n=6 to 8 and with d=0.15 mm to 0.29 mm, wherein this construction means that the steel cord (10) has 2 to 4 twisted-together strands (11), wherein each strand (10) contains 6 to 8 steel filaments (12), in that each steel filament (12) of the steel cord (10) has the same filament diameter (13) and in that the sum of the twist angle α of a strand (11) and the twist angle β of the steel cord lies between 37° and 50°, preferably between 37° and 45°, particularly preferably between 38.5° and 42.5° and most particularly preferably between 39.3° and 41.3°.
