A tire comprising a carcass-type reinforcement structure and beads, each bead being extended radially outwardly by a sidewall, the sidewalls meeting radially outwardly with a tread, the intersection of the sidewalls and of the tread defining the shoulder ends of the tire. The tire includes, in the area of each of the sidewalls, at least one layer of materials having a stretch rigidity in the longitudinal direction greater than 5000 daN/mm and the radially outer end of said layer of materials is radially inside the shoulder ends of the tire. |

1. A tire comprising:
a carcass-type reinforcement structure, including reinforcing elements; beads, the base of which is configured to be fitted on a rim seat, each bead being extended radially outwardly by a sidewall, the sidewalls meeting radially outwardly with a tread, the intersection of the sidewalls and of the tread defining shoulder ends of the tire; under the tread, a crown reinforcement structure; in the area of each of the sidewalls, at least one layer of materials having a stretch rigidity in the longitudinal direction greater than 5000 daN/mm, wherein a radially outer end of said layer of materials is radially inside the shoulder ends of the tire; and on the outer surface of each of the sidewalls, a boss extending circumferentially, the radius of curvature of which is between 8 and 20 mm, wherein, for each of the sidewalls, a portion of the carcass-type reinforcement structure has a curvature similar to the curvature of the boss, and wherein, for each of the sidewalls, the sidewall radially inside the boss has a first inflection point and the sidewall radially outside the boss has a second inflection point. |
