Patent ID: 7278458

Claim:
A tire designed to be mounted on a mounting rim, the tire comprising: two beads designed to cooperate with respective seats of the mounting rim, each of the beads comprising an annular bead reinforcement structure; a tread; a crown comprising a crown reinforcement structure, the crown being surmounted radially on the outside by the tread; on either side of the crown, a sidewall extending from the crown to the respective bead; and a carcass reinforcement extending between the beads, passing through the crown and the sidewalls, wherein at least one sidewall comprises at least two annular sidewall reinforcement structures, each annular sidewall reinforcement structure having an inner diameter at least equal to a maximum diameter D c of the mounting rim, wherein the carcass reinforcement is anchored at least partially on each annular bead reinforcement structure and on each annular sidewall reinforcement structure, wherein the at least two annular sidewall reinforcement structures comprise a radially innermost annular sidewall reinforcement structure and a radially outermost annular sidewall reinforcement structure, wherein the difference between the inner diameter of said radially innermost annular sidewall reinforcement structure and a diameter D j of the seat of the mounting rim on the same side as the sidewall containing the at least two annular sidewall reinforcement structures is at least equal to 20% of the diameter D j , and wherein the difference between the inner diameter of said radially outermost annular sidewall reinforcement structure and the diameter D j is at most equal to 1.6 times a section height H of the tire.
