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 and 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<LE<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.
