A tire includes at least one body defining a plurality of body ply layers, and a toroidal element located between the body ply layers. The toroidal element includes inner and outer regions formed by the body ply layers, and a central region formed by an inner rubber component located between the body ply layers. At least a portion of the central region is more elastic than the inner and outer regions. The toroidal element includes a first sidewall portion extending along at least a portion of the first sidewall region of the tire, and a second sidewall portion extending along at least a portion of the second sidewall region of the tire. The toroidal element is pre-stressed such that the first sidewall portion of the toroidal element exerts a first axially outward force, and such that the second sidewall portion of the toroidal element exerts a second axially outward force.
