Abstract
A self-supporting tyre for a vehicle wheel includes a carcass structure, a belt structure, a tread band, a pair of sidewalls, and at least one elastic stiffening insert. The carcass structure includes at least one carcass ply provided with end flaps engaged with respective annular reinforcing structures. The annular reinforcing structures are disposed in coaxial relationship with a geometric rotation axis of the tyre at positions axially spaced apart from each other. Each annular reinforcing structure includes at least one first circumferentially inextensible annular anchoring insert. The at least one elastic stiffening insert is incorporated into the carcass structure, at least at one of the sidewalls, and includes a radially internal end portion at least partly disposed in axial side-by-side relationship against the at least one first annular anchoring insert. A method of making the tyre is also disclosed.
