The invention relates to a tyre comprising a working reinforcement comprising a single working ply, a carcass reinforcement and a hoop reinforcement. The hooping reinforcing textile filamentary element or elements (480), the working reinforcing filamentary elements (460) and the carcass reinforcing filamentary elements (440) are arranged so as to form a triangular mesh in projection on the circumferential equatorial plane (E). The or each hooping reinforcing textile filamentary element (480) is formed by a cord (30) with a triple twist (T1, T2, T3), comprising an assembly (25) consisting of N>1 strands (20a, 20b, 20c) twisted together with a twist T3 in a direction D2, each strand consisting of M>1 pre-strands, which are themselves twisted together with a twist T2 (T2a, T2b, T2c) in a direction D1 opposite to D2, each pre-strand itself consisting in a yarn that has been previously twisted about itself with a twist T1 in the direction D1, wherein at least half of the N times M yarns consist of elementary monofilaments of aromatic polyamide or aromatic copolyamide.
