ABSTRACT:
A tire carcass structure includes at least one carcass ply and a pair of annular reinforcing structures. The at least one carcass ply includes a first and second series of strip segments. Each strip segment extends around a cross-section profile of the carcass structure to define two lateral portions and an annulus portion. Each annular reinforcing structure includes at least one primary portion and at least one additional portion. The at least one primary portion includes a first circumferentially-inextensible annular insert and a filling body. The at least one additional portion includes at least one second circumferentially-inextensible annular insert. The first annular insert and the at least one second annular insert include one or more elongated elements extending in substantially-concentric turns. A radial extension of the at least one second annular insert is less than a radial extension of the first annular insert.
