    Abstract: 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).

    Abstract: A pneumatic tire includes a tread, sidewalls extending from edges of the tread, clinches extending from the edges of the sidewall, beads positioned on axially inner side of the clinches, a carcass bridging the beads along inner side of the tread and sidewalls, and load support layers positioned on axially inner side of the carcass such that the layers are positioned between the tread and beads. Each bead includes core and main apex, the core has radially outer side surface facing radially outward, the carcass includes carcass ply turned up around the core from inner side toward outer side in axial direction of the tire such that the main portion and turn-up portion are formed in the ply, the turn-up portion has core laminating portion laminated on the radially outer side surface of the core, and the apex is extending radially outward from radially outer side of the laminating portion.
