摘要： This invention disclosed a pneumatic tire for use on aircrafts having a tread, a crown reinforcement, and a radial carcass reinforcement. The carcass reinforcement has at least one axially inner ply of textile cord wound around a pair of bead cores, 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 one axially inner ply. Each bead has an elastomeric apex filler. The at least one axially inner ply or at least one axially outer ply has merged cords having a percent elongation at break of 12% to less than 20% and a break strength greater than 1050 N with a linear density of greater than 9,000 dtex. The preferred cord has fibers of polyamide and nylon. The cord fiber of polyamide is an aromatic polyamide 3300/2 construction. The cord fiber of nylon is a 1880/1 nylon construction. The preferred cord construction is 6.7 (A)+4.5 (N)/6.7 TPI. The cord reinforcement is preferably used in the ply layers or strips of the crown reinforcement as well.
