Tire Reinforcement
20180117970 · 2018-05-03 ·

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 A.sub.T 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 A.sub.C2 at least equal to 55 and at most equal to 80 and having an orientation opposite to angle A.sub.T of the working reinforcers so that the carcass reinforcers and the working reinforcers constitute a triangulation.

A pneumatic tire whose mounting location on a vehicle is specified and which comprises a belt disposed radially outside the carcass and composed of belt cords laid at an angle of from 15 to 40 degrees with respect to the tire circumferential direction, and a band disposed radially outside the belt and composed of first and second band cords laid at an angle of not more than 5 degrees with respect to the tire circumferential direction. The band comprises an inboard first part composed of the first band cord having a first modulus M1, and an outboard second part composed of the second band cord having a second modulus M2 more than the first modulus M1. The number of laminated plies of the band in the inboard first part is more than the number of laminated plies or a single ply of the band in the outboard second part.
