Patent ID: 7051779

Claim:
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 is located; an anchoring zone for the reinforcement structure in said bead, comprising an arrangement of circumferential 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 bonding mix of the anchoring zone having a elasticity modulus at a deformation of 10% of less than 20 MPa and preferably between 10 and 20 MPa; an axially outer zone arranged in the zone of the bead provided to be arranged between the rim hook and the anchoring zone, said zone being furnished by a rubber mix of elasticity modulus at a deformation of 10% substantially higher than that of said anchoring zone; a bearing zone for said bead extending substantially along the seat of the latter.
