The invention relates to a sulfur-crosslinkable rubberization mixture for metallic or textile strength members containing at least one novolac resin comprising alkyl urethane units and produced by reaction of a phenolic compound, an aldehyde and a carbamate resin, wherein the carbamate resin is produced by reaction of alkyl urethane with an aldehyde, and at least one etherified melamine resin. The invention further relates to a pneumatic vehicle tire which comprises at least one such sulfur-crosslinked rubberization mixture.For improved durability of the rubberized strength members, the rubberization mixture containsless than 2.5 phr (parts by weight, based on 100 parts by weight of the total rubbers in the mixture) of at least one novolac resin comprising alkyl urethane units and produced by reaction of a phenolic compound, an aldehyde and a carbamate resin, wherein the carbamate resin is produced by reaction of alkyl urethane with an aldehyde, andless than 2.5 phr of at least one etherified melamine resin.
