The invention relates to a sulfur-crosslinkable rubber coating mixture for metal or textile tire cords, said mixture containing at least one novolac resin which contains alkyl urethane units and is produced by reacting a phenol compound, an aldehyde and a urethane resin, the urethane resin is produced by reacting an alkyl urethane with an aldehyde, the mixture further containing at least one etherified melamine resin. The invention further relates to a pneumatic vehicle tyre comprising at least one such sulfur-crosslinked rubber-coating mixture. In order to improve the durability of the rubber-coated tire cords, the rubber-coating mixture contains less than 2.5 phr (parts by weight, based on 100 parts by weight of all the rubber in the mixture) of at least one novolac resin, the present invention relates to a composition comprising:-a novolac resin comprising alkyl urethane units and produced by reacting a phenol compound, an aldehyde, and a urethane resin produced by reacting alkyl urethane with an aldehyde, and-less than 2.5 phr of at least one etherified melamine resin.
