A pneumatic tire is disclosed having two annular bead portions having a bead core. A carcass extends between the bead portions through sidewall portions and a tread portion, wherein the carcass includes at least two axially inner plies which extend down from the tread and axially inward of the bead core, said at least two axially inner plies being wound around the bead core forming respective turn-ups, each turnup being located axially outward of the bead core. The carcass further includes a first axially outer ply which extends down from the tread towards the bead core and positioned axially outward of the bead core, wherein at least one of the axially outer plies is formed from reinforcements having a higher break strength than the reinforcements of the axially inner plies.

In a pneumatic tire including a carcass layer mounted between a pair of bead portions and a belt reinforcing layer disposed on an outer circumferential side of the carcass layer, the carcass layer is formed of a carcass cord made of an organic fiber cord, an elongation at break of the carcass cord is set to 20% or more, an elongation under a load of 1.5 cN/dtex of the carcass cord in sidewall portions is set to from 5.0% to 8.0%, the belt reinforcing layer is formed of a cover cord made of an organic fiber cord, and a tensile strength of the cover cord per width of 50 mm at a 3.0% elongation is set to from 2.8 kN to 4.0 kN.

A radial aircraft tire (1), defined in three main directions, circumferential (X), axial (Y) and radial (Z), comprises a crown (2) surmounted by a tread (3), two sidewalls (4), two beads (5), each sidewall (4) connecting each bead (5) to the crown (2), a carcass reinforcement (7) that is anchored in each of the beads (5) at at least one bead wire (6) and extends in the sidewalls (4) as far as the crown (2), a crown reinforcement or belt (10) that extends in the crown (2) in the circumferential direction (X) and is situated radially between the carcass reinforcement (7) and the tread (3), said carcass reinforcement (7) having at least one ply referred to as carcass ply in the form of a rubber matrix reinforced with radially oriented reinforcing elements, referred to as radial textile reinforcers, the latter being constituted entirely or partially by textile plied yarns of nylon comprising N multifilament strands twisted together to form a helix, characterized in that: N is greater than 2; the count of each strand is greater than 180 tex; the tenacity of each strand is greater than 75 cN/tex; the elongation at break of each strand is greater than 14%; the tenacity of each plied yarn is greater than 60 cN/tex; the elongation at break of each plied yarn is greater than 18%; and the helix angle of each plied yarn is greater than 20.

In a pneumatic tire including a carcass layer mounted between a pair of bead portions and a belt reinforcing layer disposed on an outer circumferential side of the carcass layer, the carcass layer is formed of a carcass cord made of an organic fiber cord, an elongation at break of the carcass cord is set to 20% or more, an elongation under a load of 1.5 cN/dtex of the carcass cord on the inner circumferential side of the belt layers is set to from 5.5% to 8.5%, the belt reinforcing layer is formed of a cover cord made of an organic fiber cord, and a tensile strength of the cover cord per width of 50 mm at a 3.0% elongation is set to from 2.8 kN to 4.0 kN.

The tire has a radial carcass reinforcement, the seat diameter of which is less than or equal to 19.5 inches, the carcass reinforcement has metal reinforcing elements which are layered cords that include several steel threads. The steel threads have a weight content of carbon C such that 0.01%C<0.4%. The at least one carcass reinforcement layer has a breaking force per unit width of between 20 daN/mm and 50 daN/mm, and the diameter of the cords is less than 0.7 mm.

A run flat tire 1 comprises a carcass 6 formed of a carcass ply 6A extending between a pair of bead portions 4 in a toroidal manner and a side reinforcing rubber layer 9 having a substantially crescent cross-sectional shape disposed on an inner side of the carcass at each of sidewall portions. steel cords 60 each including 1 to 4 filaments 61 having a strand diameter in a range of from 0.25 to 0.30 mm are arranged in the carcass ply 6A, and an outer diameter D of each of the steel cords 60 is not less than 0.62 mm.

The present invention provides a tire improved in the run flat durability, having at least one member selected from the group consisting of a side reinforcing rubber layer and a bead filler using a rubber composition comprising a rubber component containing 20% by mass or more of a modified conjugated diene based polymer, satisfying Expression (1) in terms of the elongation X under a stress of 6.5 MPa at 180 C. and the elongation Y under a stress of 6.5 MPa at 25 C. after vulcanization.
