Claim Text:
1. A tire intended to be mounted on a mounting rim of a vehicle wheel, comprising: two beads each extending to a radial height of 50% of the radial height H of the tire, each bead comprising at least one anchoring zone and a portion forming a seat intended to come into contact with the mounting rim; two sidewalls extending the beads radially outwards, the two sidewalls joining together to form a crown comprising a crown reinforcement surmounted by a tread; at least one carcass reinforcement extending from each of said two beads through the sidewall as far as the crown, each carcass reinforcement being anchored in an anchoring zone of the bead; wherein, in any radial cross section, the at least one anchoring zone of each bead each comprises a plurality of circumferentially annular reinforcing structures, said annular reinforcing structures being arranged in such a way as to form at least one anchoring alignment, said at least one anchoring alignment extending over a length LT between a radially innermost annular reinforcing structure and a radially outermost annular reinforcing structure, along a trajectory that is parallel to within 30° to a portion of the carcass reinforcement, each of said two beads further comprising, in any radial cross section, an additional stiffening reinforcement, the additional stiffening reinforcement extending between: (a) a first end situated at a distance H (b) a second end, the second end being radially at the same level as or outside of the first end and axially at the same level as or on the outside of the first end, the second end being chosen such that: a straight line connecting the first end and the second end forms an angle α (alpha) with the radial direction, the angle α (alpha) being greater than or equal to 0° and less than or equal to 90°; and wherein a distance LA separates the first end and the second end, the distance LA being greater than or equal to 30% of a mean length of the at least one anchoring alignment of annular reinforcing structures, and wherein the additional stiffening reinforcement is formed by one single alignment of at least two circumferentially annular reinforcing structures.
