Original Abstract Submitted

An aircraft radial tire, having a radial carcass reinforcement with a plurality of carcass layers made up of textile reinforcing elements oriented substantially radially, which is to say making an angle of between 75° and 105° with the circumferential direction, the radial reinforcing elements of the carcass layers are composite cords having at least one aramid filament yarn and of which the rupture force is FR, measured in accordance with the standard D885/D885M-10A (2014) and these elements exhibit a deformation at least equal to 4.6% and at most equal to 6.5% for an applied force equal to FR/4. The tenacity of these reinforcing elements is at least equal to 80 daN/mm, and the linear density of the aramid filament yarn or yarns exceeds 210 tex.
