PNEUMATIC TIRE Russian patent published in 2014 - IPC B60C15/00 B60C15/06 B60C9/08 B60C9/00 

FIELD: transport.

SUBSTANCE: in carcass (13) between the first sections (13A) where intercord distance between body section and turned over sections is gradually decreasing outwards in radial direction of tire, and the second sections (13B), where intercord distance is gradually increasing, the first sections (13C) are located with invariable distance, in which sections the turned over sections (14B) are shifted closer to body section (14A) which actually becomes neutral bending axis, and where intercord distance is constant, so that compression force acting on cords of turned over sections (14B) can be decreased.

EFFECT: higher wear resistance of bead sections in pneumatic tire.
