Tire with specified bead structure and self-sealing product and wheel assembly with same

A tire in a form of a torus that is open radially on an inside portion, the tire comprising:

• inner and outer walls, the inner wall being covered, at least in part, with an airtight layer;
• a crown;
• two beads, each bead including an annular reinforcing structure;
• two sidewalls extending from the crown to the beads;
• a crown reinforcement;
• a carcass reinforcement anchored in the beads and extending at least from the beads to the crown;
• a layer of self-sealing product covering, at least in part, the airtight layer;
• and
• a reinforcing lenticular member arranged in a sidewall region between the airtight layer and the carcass reinforcement,
• wherein each annular reinforcing structure includes a plurality of windings formed of a single metal thread,
• wherein the windings are arranged in a plurality of layers, with the layers being superposed radially,
• wherein each layer includes a group of the windings arranged side by side axially,
• wherein the layers are arranged to have a hexagonal cross section,
• wherein the reinforcing lenticular member is formed of a rubber compound and has a maximum thickness between 0.5 and 10 mm,
• wherein the carcass reinforcement includes a plurality of carcass reinforcing elements arranged adjacently and aligned circumferentially,
• wherein, for each bead, the carcass reinforcement is anchored in the bead by a turn-up around the annular reinforcing structure of the bead so as to form an outward strand and a return strand, the return strand extending radially outward as far as an end situated a radial distance DRR from a radially innermost point of the annular reinforcing structure of the bead, the radial distance DRR being greater than or equal to 7% and less than or equal to 30% of a radial height H of the tire,
• wherein each bead further includes a filling formed of at least a rubber compound, the filling being situated radially outside of the annular reinforcing structure of the bead and at least partially between the outward strand and the return strand of the carcass reinforcement,
• corresponding to the bead, the filling extending radially outside of a radially innermost point of the annular reinforcing structure of the bead as far as a radial distance DRB from the radially innermost point, the radial distance DRB being between 20 and 45% of the radial height H of the tire,
• wherein each bead further includes an outer strip formed of at least a rubber compound, the outer strip being positioned axially outside of the carcass reinforcement and of the filling, the outer strip extending radially between a radially inner end of the outer strip and a radially outer end of the outer strip, the radially inner end of the outer strip being situated a distance DRI from the radially innermost point of the annular reinforcing structure of the bead, the radial distance DRI being between 1 and 10% of the radial height H of the tire, the radially outer end of the outer strip being situated a distance DRL from the radially innermost point of the annular reinforcing structure of the bead, the radial distance DRL being between 35 and 50% of the radial height H of the tire,
• wherein each bead further includes a protector formed of at least a rubber compound, the protector being structured to come into contact with a rim seat, and the protector extending axially partially outside relative to the outer strip,
• wherein, for each bead, an assembly formed by the rubber compounds of the filling, the outer strip, and the protector has a maximum thickness E, measured in any radial plane in a direction perpendicular to the outward strand of the carcass reinforcement, corresponding to the assembly, such that a ratio E/DRL is greater than 15%, and
• wherein a modulus at 10% elongation of the rubber compounds of the filling, the outer strip, and the protector is between 5 and 15 MPa.
