In a tire, a tire outer diameter OD is in a range 200 mmOD660 mm. A total tire width SW is in a range 100 mmSW400 mm. A carcass layer is formed by layering two layers of carcass plies formed by covering organic fiber cords with coating rubbers. The organic fiber cords of the two layers of the carcass plies have cord angles in a range of 80 degrees or more and 100 degrees or less with respect to a tire circumferential direction. A tensile strength Tcs per a width of 50 mm of each of the two layers of the carcass plies (13A, 13B) is in a range 17 N/mmTcs/OD120 N/mm with respect to the tire outer diameter OD.

A tire with a tread reinforcing layer that includes a ply reinforcing structure formed by winding a cord-embedded rubber tape circumferentially of the tire. The ply reinforcing structure includes first oblique segments and second oblique segments which intersect with each other to form a mesh structure having rhombic spaces. The circumferential lengths of the rhombic spaces are less than times the maximum circumferential length of the ground contacting patch of the tire in its normally loaded state.

A tire comprising a crown reinforcement formed from at least two working crown layers of reinforcing elements and at least one layer of circumferential reinforcing elements, wherein, the tensile modulus of elasticity at 10% elongation of at least one skim coat of at least one working crown layer is greater than 9 MPa and the maximum value of tan(), denoted tan()max, of said skim coat is less than 0.100.

Crown reinforcement of an aircraft tire with improved mechanical strength in order to increase the burst pressure of the tire, during a standard pressure test. An aircraft tire comprises a working reinforcement made up of a strip (5) wound continuously in a zigzag, from a starting end (51) to an ending end (52), in a circumferential direction (XX) of the tire, along a periodic curve (7) forming a non-zero angle A with the circumferential direction (XX) of the tire and in an equatorial plane (XZ) of the tire. The starting end (51) and the ending end (52) of the strip (5) are positioned axially at a distance (DI, DF) at most equal to 0.25 times the axial width W.sub.T of the working reinforcement from an axial end (E1, E2) of the working reinforcement.

A cord of a band of a tire has a single-stranded structure in which steel filaments are stranded, and the number of the filaments is not less than three and not greater than six. In a cross-section of the cord, when represents a diameter of a smallest circle that surrounds cross-sections of the filaments, and represents a diameter of each filament, a gap is formed between the filaments such that the diameter is not less than three times the diameter and not greater than six times the diameter in the case of the number of the filaments being three or four. An initial elongation of the cord is not less than 0.1% and not greater than 1.5%.

A pneumatic tire may include: a carcass; a belt reinforcing structure comprising a plurality of belt layers that include at least one spiral belt layer and at least one zigzag belt layer; and a tread comprising two or more main grooves extending circumferentially continuously around the pneumatic tire and defining a plurality of ribs that include two axially outermost ribs.
