Abstract: A heavy truck tire is provided that includes a tread and a casing. The casing has a bead with a bead core having padding gum and a rod with a perimeter. A contention armature surrounds the bead core and has an overlap, a majority of which is located outward in the radial direction from the rod. The padding gum is arranged in relation to the rod such that an outer area, inner area, and an axially outer area of the padding gum have areas that are greater than or equal to 20% of the area of the perimeter of the rod. An axially inner area of the padding gum is greater than or equal to 10% of the area of the perimeter of the rod.

Abstract: Aircraft tire comprises carcass reinforcement (5) comprising a first family of carcass layers extending between two beads (3), having at least one carcass layer wrapped, within each bead, from the inside towards the outside of the tire, around a bead wire (6) to form turn-up (511) having free end (E1) radially outside of radially outermost point (E) of the bead wire. The second family comprises at least two carcass layers, adjacent each to the next, extending, within each bead, from outside towards inside of the tire, as far as their respective ends (E2) which are radially inside of axial straight line (DY) through centre (O) of bead wire (6) and axially inside of a radial straight line (DZ) through centre (O) at axial distance (d2) at least equal to 5 mm. The carcass layers of the second family are axially inside of at least one turn-up of a carcass layer of the first family.

Abstract: A tire having a radial carcass reinforcement, composed of at least one layer of metal reinforcing elements, the said tire comprising a crown reinforcement, itself topped radially by a tread, the said tread being joined to two beads via two sidewalls. The metal reinforcing elements of at least one layer of the carcass reinforcement are cords exhibiting, in the “permeability” test, a flow rate of less than 20 cm3/min and at least one layer of the carcass reinforcement is provided, on at least one face, with textile threads exhibiting, in the “permeability” test, a flow rate of between 1 and 3 cm3/min.

Abstract: The tire comprises a tread, a crown reinforcement and at least one crown layer. The crown layer has an axial width (L2) that is at least two-thirds of a maximum axial width (L1) of the tire and has a concave portion with axial limits (M2, M?2) on either side of an equatorial plane (XZ). The tire further includes a carcass reinforcement which has at least one carcass layer with a concave portion that has axial limits (M3, M?3) on either side of the equatorial plane (XZ). The radial distance (d) between the respective concave portions is at a maximum in the equatorial plane (XZ) and decreases continuously from the equatorial plane (XZ) as far as the axial limits (M2, M?2) of the said concave portions axially closest to the equatorial plane (XZ), where it reaches a minimum value (dM).

The metal reinforcing elements of at least one layer of the carcass reinforcement are non-wrapped cords which, in the test referred to as the permeability test, return a flow rate of less than 20 cm3/min, in a radial plane, at least over part of the meridian profile of the tire, the thickness of rubber compound between the interior surface of the cavity of the tire and the point of a metal reinforcing element of the carcass reinforcement closest to the interior surface of the cavity is less than or equal to 3.8 mm and the ratio between the thickness of rubber compound measured at the circumferential mid plane and the said thickness measured in another region of the tire is greater than 1.05.
