HIGH-CAPACITY VEHICLE TIRE WITH CIRCULAR REINFORCING ELEMENTS

摘要

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. Ratio between crown area depth at shoulder end and crown area depth in circumferential median plane is larger than 1.20. Ratio between spacing between maximum wear surface and reinforcing elements in said plane and spacing between maximum wear of reinforcing elements at the ends of said layer of said elements varies from 0.95 to 1.05.EFFECT: higher fatigue strength.14 cl, 3 dwg
