Abstract:
A tire (10) for two-wheeled vehicles comprises a crown (12) comprising: a tread (20), and a hoop reinforcement (17) comprising at least one hooping ply (19) comprising one or more hoop reinforcing elements (44) comprising an assembly made up of a multifilament strand of aromatic polyamide or aromatic copolyamide (47) and of a multifilament strand of aliphatic polyamide (48). The twist factor K of the hoop reinforcing element (44) ranges from 5.5 to 6.5. The tire (10) is obtained by a method comprising a step of manufacturing the hooping ply (19), in which the bonded reinforcing elements (44) are embedded in a polymer composition in order to form the uncured hooping ply, the equivalent initial tensile modulus of the uncured hooping ply ranging from 330 to 620 cN/tex/dm.
