FIELD: machine building.
SUBSTANCE: tire (10) contains at least one carcass layer (28), which contains one or more reinforcing elements (36). Tire (10) is obtained using a method comprising a step of manufacturing each carcass layer (28), in which one or more glued frame reinforcing elements (36) are immersed in the polymer composition to form each uncured frame layer (27), wherein the ratio of the tangent modulus at the equivalent force generated by the green layer at 7% elongation to the secant modulus at the equivalent force generated by the green layer at 1% elongation is greater than or equal to 2.00. Density of carcass reinforcing elements (36) in uncured carcass layer (27) is from 50 to 150 carcass reinforcing elements (36) per decimetre of uncured carcass layer (27), and each frame reinforcing element (36) forms an angle greater than or equal to 85°, with tire circumferential direction Z (10).
EFFECT: improved tire performance.
