摘要： The invention relates to a tyre comprising a crown reinforcement formed of at least two working crown layers, of at least one layer of circumferential reinforcing elements positioned radially between two working crown layers, the working crown layers adjacent to the layer of circumferential reinforcing elements lying on each side of the equatorial plane and in the axial continuation of the layer of circumferential reinforcing elements coupled across an axial width in order subsequently to be uncoupled. According to the invention, a first additional layer of polymer compound of a width at least equal to the width l of the coupling zone and of a maximum thickness less than twice the thickness of the layer of circumferential reinforcing elements is positioned radially under the radially adjacent working crown layer and on the inside of the layer of circumferential reinforcing elements and is at least partially radially superposed on the region at which the working crown layers are coupled.

摘要： The invention relates to a tyre including at least two working layers (41, 43) and at least one layer of reinforcing elements (42). According to the invention, the layer of circumferential reinforcing elements (42) is formed by at least one central part (422) and two axially outer parts (421). The penetration rate of the circumferential reinforcing elements of the central part (422) by the associated rubber mixture coating is less than the penetration rate of the circumferential reinforcing elements of the axially outer parts (421) by the associated rubber mixture coating.

摘要： The invention relates to synthetic branched polyisoprenes having a macrostructure and a microstructure which are very similar to those of natural rubber. According to one aspect of the invention, said polyisoprenes have an apparent stress F/S0 which is equal to or greater than 0.4 MPa for an elongation α of 150 % which is applied to a dumb-bell-shaped test piece containing cross-linkable polyisoprene. According to another aspect of the invention, said polyisoprenes satisfy relation (i) Cotan δ = 0.3761. θinh + 0.15, wherein: cotan δ is the cotangent of the loss angle of a sample of the polyisoprene, which is measured at 130° C using a device with the trade name RPA2000, said sample being shear stressed at 10 % of deformation and at a stress frequency of 0.035 Hz; and θinh is the inherent viscosity of the polyisoprene, which is measured in toluene at 25° C and with a 0.1 g/dl concentration of polyisoprene in the toluene.
