The invention relates to a rubberized reinforcing ply for articles made of elastomeric material, preferably for vehicle tires, where the reinforcing ply has a multiplicity of parallel strengthening elements spaced apart from one another, with each strengthening element consisting of polyamide 6.6 and having an x1 construction, hence being a twisted multifilament yarn of polyamide 6.6. The crude yarn 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 multifilament yarn has a tenacity which, at an elongation of 4%, is within a range from 2.0 cN/dtex to 2.8 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 77° C. are determined under a pre-tension of 0.045 g/dtex with an exposure time of two minutes.
