A separate-tread radial tyre (1) comprises a load-bearing structure (2) and a tread ring (3) associated with the load-bearing structure (2) in a radially external position thereto through a shape coupling. A carcass ply (8) of the load-bearing structure (2) comprises a central portion (8a) that extends between two annular anchoring structures (9) arranged at an inner diameter of the tyre corresponding to the keying diameter of the tyre on a respective mounting rim, and two end portions (8b) that extend continuously from the central portion (8a) to a free edge (10). Each end portion (8b) is turned back around one of the annular anchoring structures (9) and arranged along the profile defined by the central portion (8a), externally thereto. Each end portion (8b) has along the profile defined by the central portion (8a), between the respective annular anchoring structure (9) and the free edge (10), a length (L) greater than the length of the respective annular anchoring structure (9) such that the free edge (10) is arranged beyond the annular anchoring structure itself, leaving a central deflating portion (11) free, delimited by the free edges (10).
