Radial tire for heavy vehicle comprises carcass layer (3) comprising main part (31) wrapped, in each bead (1), from inside to outside of the tire, around bead wire (4), to form turn-up (32). Distance (d) between turn-up (32) and main part (31) decreases continuously, radially towards the outside, from bead wire (4), and passes through minimum value (d1). Carcass layer (3) has parallel reinforcers coated in coating compound (33), and filling element (5) extending axially between turn-up (32) and main part (31) and radially outwards from bead wire (4). Filling element (5) comprises two filling compounds (51, 52) extending radially outwards from bead wire (4). Compound (51) has a modulus of elasticity at 10% elongation at least equal to the modulus of elasticity of the second (52), which has a modulus of elasticity at 10% elongation equal to the modulus of elasticity at 10% elongation of coating compound (33).
