Abstract:
1. A tire comprising at least a carcass-type reinforcement structure, consisting of at least one layer of carcass reinforcement elements, anchored on either side of the tire to a bead whose base is intended to be mounted on a rim seat, each bead being extended radially towards the outside by a sidewall, the sidewalls meeting up radially towards the outside with a tread, and comprising under the tread a crown reinforcement structure comprising a layer of axially continuous circumferential reinforcement elements, wherein, in accordance with the profile of the tire in a radial plane, said layer of circumferential crown reinforcing elements extends in the sidewalls beyond the two points of tangency of the curvilinear abscissa of the carcass-type reinforcement structure with perpendiculars to the axis of rotation, wherein the part of the layer of circumferential elements, radially to the outside of the two points of tangency of the curvilinear abscissa of the carcass-type reinforcement structure with perpendiculars to the axis of rotation is at least in part radially to the inside of the part of the carcass-type reinforcement structure radially to the outside of the two points of tangency of the curvilinear abscissa of the carcass-type reinforcement structure with perpendiculars to the axis of rotation, wherein the part of the layer of circumferential elements, radially to the inside of the two points of tangency of the curvilinear abscissa of the carcass-type reinforcement structure with perpendiculars to the axis of rotation is radially to the inside of the carcass-type reinforcement structure radially to the inside of the two points of tangency of the curvilinear abscissa of the carcass-type reinforcement structure with perpendiculars to the axis of rotation and, wherein said circumferential reinforcement elements of said layer are distributed in the transverse direction with a variable pitch in the part of the layer of circumferential elements radially to the outside of the two points of tangency of the curvilinear abscissa of the carcass-type reinforcement structure with perpendiculars to the axis of rotation.
