摘要： The invention relates to the reinforcement that reinforces a passenger vehicle tyre. It targets good resistance to penetration and perforation of its crown by foreign objects, with a reinforcing architecture that is simple and lightweight. According to the invention, the hooping layer (71) has a breaking strength per mm of axial width of the hooping layer FR at least equal to 35 daN/mm, an elongation at break AR at least equal to 5% and a secant extension modulus MA at least equal to 250 daN/mm, for an applied force F equal to 15% of the rupture strength FR of the said hooping layer (71). The working reinforcement (6) comprises a single working layer (61) of which the working reinforcements form, with the circumferential direction (YY'), an angle A
T at least equal to 30° and at most equal to 50°. The carcass reinforcements of the at least one carcass layer (81) form, with the circumferential direction (YY') and in the equatorial plane (XZ), an angle A
c2 at least equal to 55° and at most equal to 80° and having an orientation that is the opposite of that of the angle A
T of the working reinforcers, so that the carcass reinforcers and the working reinforcers constitute a triangulation system.

摘要： The invention relates to a tire, which includes a knitted fabric (44), including: columns (C1, C2, C3, C4) of loops (B), the loops (B) of a single column (C1, C2, C3, C4) being arranged, one after the other, substantially in a so-called "main" general direction (X1); and rows (R1, R2, R3, R4) of loops, the loops (B) of a single row (R1, R2, R3, R4) being arranged, one beside the other, substantially in a so-called "transverse" general direction (Z1). The knitted fabric (44) has, in the main general direction (X1) and/or transverse general direction (Z1), a force no lower than 250 N when 100% elongated. The force when 100% elongated is determined on the basis of a force/elongation curve obtained by applying ISO standard 13934-1:2013 to the knitted fabric (44) embedded in a standard elastomer matrix.
