Tire comprising two beads (20), two sidewalls (30) joining in a crown, and at least one carcass reinforcement (60) extending from the beads through the sidewalls to the crown, the carcass reinforcement being anchored in the two beads by a turn-up around an annular reinforcing structure in such a way as to form in each bead an incoming portion (61) and a wrapped-around portion (62), wherein each bead comprises a bead filler (110) and an outer band (120), the latter being placed axially outside of both the carcass reinforcement and the bead filler, wherein the assembly formed by the bead filler (110) and the outer band (120) has a thickness E(r), r being the distance to the radially innermost point (71) of the annular reinforcing structure, the thickness E(r) at different positions being such that, in the range of distances r greater than or equal to 15% and smaller than or equal to 50% of the radial height H of the tire, the variation of the thickness is less than or equal to −0.25 mm/mm over at least 5 mm.
