Abstract: A tire (10) comprises: a crown (12) surmounted by a tread (20), two sidewalls (22), two beads (24), each sidewall (22) connecting each bead (24) to the crown (12), a carcass reinforcement (32) anchored in each of the beads (24) and extending from each bead (24) through each sidewall (22) and comprising textile filamentary carcass reinforcing elements, a sidewall reinforcing reinforcement (25) comprising textile filamentary sidewall reinforcer reinforcing elements. R=max(K1,i)/min(K2,j)>1 where K1,i is the twist factor of each of the i carcass multifilament textile plied strands of each textile filamentary carcass reinforcing element, and K2,j is the twist factor of each of the j sidewall reinforcer multifilament textile plied strands of each textile filamentary sidewall reinforcer reinforcing element.

Abstract: The reinforcing element (45) comprises an assembly (49) made up: of a multifilament strand made of aromatic polyamide or aromatic copolyamide (46) and of a multifilament strand made of polyester (48). The two strands (46, 48) are wound in a helix around one another, and the reinforcing element (45) is twist-balanced. The twist factor K of the reinforcing element (45) ranges from 5.5 to 6.5 where K is defined by the formula: K=(R×Ti1/2)/957 in which R is the twist of the reinforcing element (45) expressed in twists per metre and Ti is the sum of the counts of the multifilament strands of the reinforcing element (45) in tex.

Abstract: Breaking energy test performance of lightweight tyres that have a good performance in terms of rolling resistance and having a nominal width at least equal to 135 mm and at most equal to 235 mm is increased. These tyres comprise two thin and lightened working layers (41, 42) comprising metal reinforcing elements (411, 421) made up of monofilaments having a linear breaking strength Rct at least equal to 300 daN/cm and at most equal to 400 daN/cm, and a single carcass layer (6) radially on the inside of the working layers. In order to improve performance in the breaking energy test, this carcass layer comprises textile reinforcing elements and has surface breaking energy at least equal to 1.75 J/cm2.

Abstract: Breaking energy test performance of lightweight tyres that have a good performance in terms of rolling resistance is increased. These tyres comprise two thin and lightened working layers (41, 42) comprising metal reinforcing elements (411, 421) having a linear breaking strength Rct at most equal to 400 daN/cm, and a single carcass layer (6) radially on the inside of the working layers. In order to successfully undergo the “breaking energy” test, this carcass layer comprises textile reinforcing elements that have an elongation at break Acc at least equal to 15%, the carcass layer having a linear breaking strength Rcc at least equal to 0.55 times the linear breaking strength of the working layers.
