摘要： The rolling resistance of a tire has been improved without degrading industrial performance. The sidewall (30) consists of two sub-layers. A first sub-layer (FE1) of thickness E1 and volume V1 provides the expected protection functions of a sidewall as the outer wall of the tire, and a second sub-layer of the sidewall (FE2) of thickness E2 and volume V2 is optimized at low hysteresis to improve rolling resistance. The ratio V1/(V1+V2) of the volumes of the two sub-layers (FE1, FE2) is less than or equal to 0.3. The elongation at break of the compound of FE1 is greater than or equal to 200% measured at a temperature of 100° C., and the viscoelastic loss of the compound of FE2, Tan(δ)max, is less than or equal to 0.10.

摘要： The invention relates to a tyre (10) comprising a hooping ply (19) comprising at least one textile wire-like hoop reinforcer element making an angle strictly less than 10° with the circumferential direction (Z) of the tyre (10). The bonded textile wire-like reinforcer element has, before the step of production of the hooping ply (19), a tangent modulus less than or equal to 5 cN/tex/% for any elongation less than or equal to 3%. The textile wire-like hoop reinforcer element has, once extracted from the tyre (10), a tangent modulus greater than or equal to 5 cN/tex/% for any elongation greater than or equal to 4%.

摘要： A tire (10) comprises a crown (12) comprising a tread (20), a crown reinforcement (14), a carcass reinforcement (32), two side walls (22), two beads (24), each side wall (22) linking each bead (24) to the crown (12), the crown reinforcement (14) extending in the crown (12) in a circumferential direction (Z) of the tire (10). The textile wire-like hoop reinforcer element (48), the wire-like working reinforcer elements (46) and the wire-like carcass reinforcer elements (44) are arranged so as to define, in projection on the equatorial circumferential plane (E), a triangular mesh. The textile wire-like hoop reinforcer element comprises a core composed of a first strand comprising at least one monofilament, and a layer comprising at least two second strands, each second strand comprising at least one monofilament, each second strand of the layer being helically wound around the core.

摘要： A tire for a motor vehicle comprising: two beads (20); two sidewalls (30) meeting at a crown (25); at least one carcass reinforcement (160) extending from the beads (20) through the sidewalls (30) as far as the crown (25), the carcass reinforcement (160) having a plurality of carcass reinforcing elements and anchored in the two beads (20) by a turn-up around the annular reinforcing structure (70), so as to form in each bead a main strand (162) and a turn-up strand (163); and a stiffening reinforcement (140) arranged in at least one sidewall of the tire, said stiffening reinforcement (140) having a radially inner end (141) and a radially outer end (142), the stiffening reinforcement being formed of a plurality of stiffening elements oriented at an angle less than or equal to 10° relative to a circumferential direction of the tire.
