Abstract:
A pneumatic tire for use on aircrafts having a nominal bead diameter NBD, a tread, a crown reinforcement, and a radial carcass reinforcement comprising at least one axially inner ply of textile cord wound around a pair of bead cores, the bead cores have a radial height BH, the at least one axially inner ply being wound around the bead core in each bead from inside to the outside forming outside turn-ups and at least one axially outer ply of textile cords extending from bead to bead along the turn-ups of the at least axially inner ply, each bead having a rim flange vertical surface and an elastomeric filler of substantially triangular shape, the apex A of the filler being located above the bead core and the rim flange vertical surface extending a distance D as measured from a line YYâ€² parallel to the axis of the tire and passing through the location of the nominal bead diameter NBD, the tire characterized by:a flipper wound around the bead core to form an axially inner leg and an axially outer leg, the axially inner leg being located at a radial distance LI from the reference line YYâ€² and the axially outer end leg being located a radial distance LE from the reference line YYâ€² and the flipper being oriented where BHE and LI<0.7D; and the at least one axially inner ply has at least one turnup below the location A; and LE, LI, and the at least one turnup below the location A being radially between the bead core height and the radially outer end of the rim flange vertical surface.
