Extended-mobility tire with decoupled anchoring zone

A tire for a vehicle wheel, comprising:

• two sidewalls spaced apart axially from each other, joined at their radially outer portions by a crown zone provided on its radially outer portion with a circumferential tread;
• beads, 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:
• a bead seat comprising a generatrix the axially inner end of which is located on a circle of diameter greater than the diameter of the circle on which the axially outer end thereof is located;
• an anchoring zone for the reinforcement structure in said bead, comprising an arrangement of circumferential first cords arranged substantially adjacent to a portion of the reinforcement structure and comprising at least two stacks distributed on either side of the reinforcement structure, a bonding mix being arranged between the circumferential cords and the reinforcement structure, said anchoring zone being arranged in said bead in such a manner that, at normal pressure, the forces of the reinforcement structure are distributed substantially homogeneously on either side of said reinforcement structure, in said anchoring zone, said reinforcement structure comprising second cords arranged so as to obtain a circumferential distribution of the second cords on opposite sides of at least one of said stacks;
• a bearing zone for said bead extending substantially along the seat of the latter;
• said tire also comprising an external lateral zone arranged in the zone of the bead provided to be arranged between the rim hook and the anchoring zone, said zone being filled by a rubber mix of substantially high modulus.
