Vehicle tire comprising looped crown reinforcement and circumferentially oriented crown reinforcement elements

A motorcycle tire comprising a carcass-type reinforcement structure, formed of reinforcement elements and anchored on each side of the tire to a bead whose base is intended to be fitted 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 at least one layer of working reinforcement elements constituting a working layer, said crown reinforcement structure comprising at least one additional layer of circumferentially oriented reinforcement elements entirely radially to the outside of the carcass-type reinforcement structure, wherein, over the profile of the tire in a radial plane, in its part 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, at least one layer of working reinforcement elements is at least partially radially to the inside of the part of the carcass-type reinforcement structure radially to the outside of the two points of tangency,

• wherein the at least one layer of working reinforcement elements comprises at least one continuous reinforcement cord forming, in a central zone of said layer, portions having identical angles formed with the longitudinal direction, said angles being measured at the points of intersection with a circumferential plane, wherein two adjacent portions are linked by a loop, and wherein the portions form an angle with the longitudinal direction of between 10 and 80°, wherein the angles formed by said portions with the longitudinal direction are variable in the transverse direction and wherein said angles are greater at their axially outer edges than at the level of an equatorial plane of the tire, wherein the angles of the portions continuously increase in monotonic manner from the equatorial plane of the tire as far as the edges of the working layer, wherein the largest angles of said portions approach 90°.
