Heavy vehicle tire with two beads (2) contacting rim (3) an outer face (21), radial carcass reinforcement (4) having carcass layer (41) wound within each bead (2) around bead wire (5) having center (O) to form turnup (411), additional circumferential reinforcement (6), in each bead (2), having additional layer (61, 62), additional reinforcement (6) extending radially from radially inner end (E1) to radially outer end (E2) and axially on outerside of axially outermost turnup (411). The orthogonal projection (P1) of radially inner end (E1) of additional circumferential reinforcement (6) onto axially outer face (21) of bead (2) is radially on outside of center (O) of bead wire (5), the orthogonal projection (P2) of radially outer end (E2) of additional circumferential reinforcement (6) onto axially outer face (21) of the bead (2) contacting point (P′2) of rim (3) that is axially on inside of point (C) of last contact of rim (3) when tire (1) is mounted and inflated, and radial distance (d) between end (E1) and end (E2) of additional circumferential reinforcement (6) is at most 20 mm.
