A tire designed to be mounted on a mounting rim J of maximum diameter D<SUB>c </SUB>the type comprising beads designed to cooperate with seats of the mounting rim, the beads comprising at least one annular bead reinforcement structure; a crown comprising a reinforcement structure, this crown being surmounted radially on the outside by a tread; on either side of the tire's crown, a sidewall providing connection to each bead; a carcass reinforcement extending between the crown and the beads; wherein at least one sidewall comprises at least two additional annular reinforcement structures, each additional annular structure having an inner diameter at least equal to the maximum diameter D<SUB>c </SUB>of the rim; the carcass reinforcement is anchored at least partially on each annular bead reinforcement structure and on each additional annular sidewall reinforcement structure; the difference between the inner diameter of the radially innermost additional annular reinforcement structure in each sidewall and the diameter D<SUB>j </SUB>of the rim seat on the same side as the sidewall containing the annular structure is at least equal to 20% of the diameter D<SUB>j</SUB>.
