Abstract
A tire includes a tread formed in a crown region of the tire and sidewall regions extending from the crown region to bead areas. The tire further includes a toroidal element extending across a crown region of the tire, and further extending along at least a portion of each sidewall region of the tire. The toroidal element has a central region located between inner and outer regions. The central region is more elastic than the inner and outer regions.

A tire having a crown region and a pair of sidewall regions, the tire comprising:
- a pair of beads, including a first bead and a second bead;
- a body ply having a main portion which extends circumferentially about the tire from the first bead to the second bead, a first turned-up portion around the first bead, and a second turned-up portion around the second bead,
- wherein the first turned-up portion has a first end in the crown region of the tire,
- wherein the second turned-up portion has a second end in the crown region of the tire, and
- wherein the first turned-up portion overlaps the second turned-up portion;
- a toroidal element,
- wherein the toroidal element includes an outer region formed by the body ply turned-up portions, an inner region formed by the body ply main portion, and a central region formed by an inner rubber component located between the main portion of the body ply and the turned-up portions of the body ply,
