A vehicle tire having two beads comprising metal/non-metal hybrid bead cores intended to come into contact with a wheel rim and a carcass reinforcement anchored by a bead core located in each bead, wherein the bead core includes a plurality of separate spirally-wound reinforcements that are placed adjacent to one another in a substantially axial arrangement. The innermost of the spirally-wound reinforcements, the one farthest from the reinforcement turn-up, is formed of a first metal wire and there is a non-metallic wire forming a second reinforcement. The metal wire has an elongation at break that is at least 40% greater than an elongation at break of the nonmetallic wire or alternatively at least 100% or at least 200% greater than the elongation at break of the non-metallic wire. Optionally wires of other metals or nonmetals may be useful for forming others of the plurality of spirally-wound reinforcements.
