A pneumatic radial ply tire (100) for use on aircraft has a radial reinforced carcass (20) having at least one axially inner ply (2A, 2B, 2C, 2D ) of textile cords (21) wound around a pair of bead cores (33). The improved bead structure (30) has a flipper (50) having an axially inner leg LI and axially outer leg LE. The ends LI, LE of the flippers (50) are above the bead core height Bh and below the apex (A) of an elastomeric strip (40) satisfying the relation Bh < LI < 0.7D and Bh < LI < 0.7D. Additionally, the tire carcass (20) has at least one axially outer ply 2E, 2F of textile cords (21) extending from bead (30) to bead (30) along the turn-ups 20A, 20B, 20C and 20D of the axially inner plies 2A, 2B, 2C and 2D. The plies (21) are closely spaced along the natural ply path. <IMAGE> |
