Abstract
Improving the endurance of the beads () of a radial tire for a civil-engineering heavy vehicle by proposing a solution which blocks the propagation of the cracks initiated in the coating elastomer of the bead reinforcing layer (), by inserting a cushion rubber () interposed between the coating elastomer of the carcass layer turn-up () and the coating elastomer of the bead reinforcing layer (). The elastic modulus in extension of the cushion rubber () measured at 100% deformation must be less than the elastic modulus of the coating compound of the carcass layer. Still according to a disclosed embodiment, the thickness of the cushion rubber () is at least equal to the thickness of the bead reinforcing layer ().
