Embodiment Construction
[0119] The figures are not drawn to scale for ease of understanding. The figures represent only a half-view of a tyre, which extends symmetrically with respect to an axis XX' representing its circumferential median plane or equatorial plane.
[0120] exist figure 1 In , a tire 1 of size 315 / 70R22.5 has an aspect ratio H / S equal to 0.70, where H is the height of the tire 1 on its mounted rim and S is its maximum axial width. Said tire 1 comprises radial carcass reinforcement 2 anchored in two beads (not shown in the figures). The carcass reinforcement is formed from a single layer of metal cords. Said carcass reinforcement 2 is hooped by a crown reinforcement 4 formed radially from the inside to the outside by:
[0121] - a first working layer 41 formed of unhooped, inextensible metal cords 9.28 continuous over the entire width of the ply and oriented at an angle equal to 24°,
[0122] - a layer 42 of circumferential reinforcing elements formed of steel metal cords 21x23 of...
