The invention relates to a tyre () comprising a hooping ply () comprising at least one textile wire-like hoop reinforcer element making an angle strictly less than 10° with the circumferential direction (Z) of the tyre (). The bonded textile wire-like reinforcer element has, before the step of production of the hooping ply (), a tangent modulus less than or equal to 5 cN/tex/% for any elongation less than or equal to 3%. The textile wire-like hoop reinforcer element has, once extracted from the tyre (), a tangent modulus greater than or equal to 5 cN/tex/% for any elongation greater than or equal to 4%.
