A tire comprises a pair of flexible bead wires (51) of reduced mass. Each bead wire (51) has the form of a closed circumferential ring, bracing the bead of the tire (1) against the rim (100) and comprising a first part made of a first material M1 taking the form of textile cords (560), the first part interacting with a second part of the bead wire (51) made of a reinforcing second material M2; the tensile stiffness is comprised between 4.5×105 N/m and 1.8×106 N/m; the circumferential bending stiffness, Kf, is greater than or equal to Kr*(1000*D/(16*25.4))3, where D is the diameter of the wheel on which the tire is mounted, measured at the seat (110) of the rim (100) in meters, and where Kr is equal to 2.10−2 N.m2; and the elastic elongation of the bead wire (51) is greater than or equal to 2%.
