FIELD: transport.
SUBSTANCE: invention relates to pneumatic tire with radial carcass reinforcement including crown area reinforcement. Crown area consists of at least two layers. Crown area reinforcement is covered radially from above by the tread connected with two beads by two side strips. Reinforcing elements of circumferential reinforcing elements are composed of twisted cords with maximum tangential modulus of elasticity in out-of-tire state is smaller the maximum tangential modulus of elasticity I initial state by over 15 GPa, preferably, by 20 GPa.
EFFECT: higher fatigue strength.
