TYRE REINFORCEMENT

Hooping layer (71) of a passenger vehicle tire has a force at break FR per mm of axial width of the hooping layer 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 FR.

Beschreibung
Zusammenfassung:	Hooping layer (71) of a passenger vehicle tire has a force at break FR per mm of axial width of the hooping layer 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 FR. Working reinforcement (6) comprises single working layer (61) the working reinforcers of which form, with circumferential direction (YY′), an angle AT at least equal to 30° and at most equal to 50°. The carcass reinforcers of at least one carcass layer (81) form, with circumferential direction (YY′) and in equatorial plane (XZ), angle AC2 at least equal to 55° and at most equal to 80° and having an orientation opposite to angle AT of the working reinforcers so that the carcass reinforcers and the working reinforcers constitute a triangulation.
