Multizone bead for a tire having extended mobility

A tire for a vehicle wheel, comprising:

• two sidewalls spaced apart axially from each other and joined at their radially outer portions by a crown zone provided on its radially outer portion with a circumferential tread;
• a bead, arranged radially to the inside of each of the sidewalls, each bead comprising a seat and an outer flange which are intended to come into contact with a suitable rim;
• a reinforcement structure extending substantially radially from each of the beads, along the sidewalls, towards the crown zone;
• at least one of said beads comprising:
• (1) a bead seat comprising a generatrix, the axially inner end of which lies on a circle of a diameter greater than the diameter of the circle on which the axially outer end is located;
• (2) an anchoring zone for the reinforcement structure in said bead, comprising a substantially radial arrangement of circumferential cords arranged in the vicinity of a portion of said reinforcement structure and comprising at least two cords distributed on each side of said reinforcement structure, and an anchoring rubber mix being disposed between said circumferential cords and said reinforcement structure;
• (3) an intermediate zone, arranged substantially axially externally to the anchoring zone and comprising at least one portion substantially radially aligned with said anchoring zone;
• and
• (4) a bearing zone for said bead which is able to lie directly or indirectly against the suitable rim seat, and comprising at least one portion axially aligned with said intermediate zone and placed radially internally with respect to said intermediate zone.
