ABSTRACT:
A toroidal insert for an inflated, tubeless, pneumatic tire. The insert comprises a preformed torus-like core, tire cord radially wound around the torus-like core, and at least one load bearing member having tire cord therein, said member being circumferentially wound around substantially the middle one third of the radially outer surface of the radially wound tire cord. The insert, when situated within the inflated tire, includes a cross-section having a thick, substantially oval, central portion extending between the beads of the inflated tire and a pair of thin end portions each extending from its respective side of the thick, oval, central portion along the adjacent sidewall of said inflated tire to about the midpoint of said adjacent sidewall, whereby, when the tire is deflated, the thick, oval, central portion of the insert supports the tread portion of the deflated tire and each of the thin end portions of the insert lies between and supports the adjacent, collapsed sidewall of the deflated tire.
