HEAVY GOODS VEHICLE TYRE

摘要

The invention relates to a tyre with a radial carcass reinforcement comprising a crown reinforcement formed of at least two working crown layers of inextensible reinforcing elements, 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 to be decoupled subsequently. According to the invention, a layer of polymer compound of a thickness greater than 1.5 mm across an axial width in excess of 0.1 ´ d is positioned axially between the axially exterior end of the layer of circumferential reinforcing elements and the axially interior end of the region at which the working crown layers are coupled.
