Abstract: 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.

Abstract: A pneumatic tire 2 includes a buttress reinforcing layer 22. A carcass 12 includes a first ply 38 and a second ply 40. The first ply 38 and the second ply 40 each have a main portion that is extended on and between beads 10 on both sides. The buttress reinforcing layer 22 extends along the first ply 38 and the second ply 40 between the first ply 38 and the second ply 40. An outer end 22a of the buttress reinforcing layer 22 is disposed inward of a shoulder region S of a tread 4 in a radial direction. An inner end 22b of the buttress reinforcing layer 22 is disposed at a maximum width position of the tire or disposed outward of the maximum width position of the tire in the radial direction.

Abstract: A non-pneumatic tire has a crown region and a pair of sidewall regions, including a first sidewall region and a second sidewall region. The non-pneumatic tire includes a pair of beads, including a first bead and a second bead, and a toroidal element. The toroidal element includes an inner region, an outer region, and a central region. At least a portion of the central region is more elastic than the inner and outer regions. The toroidal element includes a crown portion extending across the crown region of the non-pneumatic tire, a first sidewall portion extending along at least a portion of the first sidewall region of the non-pneumatic tire, and a second sidewall portion extending along at least a portion of the second sidewall region of the non-pneumatic tire. The toroidal element is pre-stressed such that when the non-pneumatic tire is mounted to a rim, the first sidewall portion of the toroidal element exerts a first axially outward force of at least 1000 pounds against the rim, and such that the second sidewall portion of the toroidal element exerts a second axially outward force of at least 1000 pounds against the rim.
