Abstract
A pneumatic commercial vehicle tire of radial design includes at least a three-ply belt, of which two belt plies are working plies and one radially outermost belt ply is a cover ply. Each of these belt plies includes reinforcements which are made of steel cord and which are embedded in elastomer. The steel cords of each of the three belt plies are coated with brass so as to provide for good elastomer adhesion. The brass coating of the reinforcement supports of the two working plies has a copper proportion of 60 wt. % to 65 wt. % and the brass coating of the reinforcement supports of the cover ply has a copper proportion of 66 wt. % to 70 wt. %.
