A tyre including two toroidal bead portions housing an annular bead bundle (121); a toroidal body ply, folded, about a respective bead bundle forming a respective turn-up; two bead fillers, each in contact with a respective bead bundle and at least partly enclosed by a respective turn-up, and two elastomeric crack control members, one for each bead portion. Each crack control member extends at a body ply ending, and each crack control member is made by a couple of strips having a differentiated stiffness along their transversal section, with a lower stiffness at a first strip adjacent to the body ply ending and a higher stiffness at a second strip in contact with the respective bundle, so that the first lower stiffness strip defines a preferential propagation path for any tyre crack originating at the body ply folded ending.
