The invention relates to a rubberized reinforcing ply for articles composed of elastomeric material, preferably for vehicle tires, wherein the reinforcing ply has a multiplicity of strengthening elements which are in parallel and spaced apart, wherein each strengthening element is a cord which is end-twisted from at least two twisted multifilament yarns composed of polyamide 6.6. The raw yarn composed of polyamide 6.6 has a tenacity which, at an elongation of 4%, is within a range from 1.35 cN/dtex to 1.60 cN/dtex, the cord has a tenacity which, at an elongation of 4%, is within a range from 1.2 cN/dtex to 2 cN/dtex and the cord has a thermal shrinkage at 177° within a range of 4.0%-7.0%, wherein the tenacity in accordance with ASTM D885-16 and the thermal shrinkage at 177° C. are determined under a pre-tension of 0.045 g/dtex with an exposure time of two minutes.
