Abstract:
1. A tire comprising: two beads configured to come into contact with a mounting rim; two sidewalls extending the beads radially to the outside; a crown joining the two sidewalls together and comprising a crown reinforcement extending axially between two axial ends and surmounted by a tread; a carcass reinforcement comprising a plurality of carcass reinforcing elements, the carcass reinforcement being anchored in the two beads and extending across the sidewalls to the crown; a hooping reinforcement, arranged radially outside the crown reinforcement, said hooping reinforcement extending from the median plane of the tire axially to the outside, on both sides of the median plane, said hooping reinforcement being formed from at least one reinforcing element oriented circumferentially; wherein in any radial section, the axial distance D between neighbouring portions of the hooping reinforcement is greater than or equal to 0.7 mm and smaller than or equal to 2 mm, with the exception of: one first axial region L two second axial regions L the sum of the axial widths of the first and second axial regions being smaller than or equal to 0.5·S, S being the maximum axial width of the tire, the axial distance D between neighbouring portions of the hooping reinforcement in the said first and second axial regions L wherein the difference between: the average axial distance between neighbouring portions of the hooping reinforcement in the said first and second axial regions L the average axial distance between neighbouring portions of the hooping reinforcement outside the said first and second axial regions L is of at least 0.2 mm; and wherein the axial distance between neighbouring portions of the hooping reinforcement is greater than 2.0 mm in the first axial region L
