1. A cellular tire insert for installation in a tire, said cellular tire insert comprising:
- a. a multiplicity of preconstructed cells comprising enclosed hollow cavities;
b. prior to being incorporated into said cellular tire insert, each of said preconstructed cells is a complete, individual structure, completely detached from any other of said cells;
c. each of said preconstructed cells comprises an external surface and an internal surface, defining one complete cell wall therebetween of a given thickness, completely enclosing a single hollow center of a given volume;
d. said cell wall is composed of an elastomeric material;
e. said hollow center of said preconstructed cells containing a gas within said hollow center under pressure above that of atmospheric;
f. said multiplicity of preconstructed, individual cells having surface portions of said external cell wall surfaces, engaged with external cell wall surface portions of adjacent cells in a state whereby substantially all of the total external cell wall surface of all cells, is in engagement with surrounding portions of external cell wall surfaces of said surrounding cells;
g. said multiplicity of preconstructed, individual cells are permanently connected together at said engaged external surface portions in said engaged state to collectively provide said cellular tire insert whereby the cells of said cellular tire insert remain in said connected and said engaged state.

Abstract
This invention is a composite cellular tire insert for insertion into the interior of pneumatic type tires to eliminate flats and blow-outs. The composite cellular tire insert is comprised of a multiplicity of preconstructed, hollow, pressurized, elastomeric, one-piece, seamless cells bonded together into a configuration whereby substantially all of the exterior cell wall surface of all cells in the tire insert, is engaged with portions of exterior cell wall surfaces of surrounding cells thereby providing a cellular tire insert that has substantially no void space or material mass between the cells.

2. A cellular tire insert for installation in a tire, said cellular tire insert comprising:
-
a. a multiplicity of preconstructed cells comprising enclosed hollow cavities; b. prior to being incorporated into said cellular tire insert, each of said preconstructed cells is a complete, individual structure, completely detached from any other of said cells; c. said preconstructed, complete, individual, detached cells have a seamless, one-piece cell wall, whereby said cells comprise an independent, one-piece external surface and an independent, one-piece internal surface, defining a complete, one-piece, seamless, independent cell wall therebetween of a given thickness, completely enclosing a single hollow center of a given volume; d. said cell wall of said preconstructed, seamless cells is composed of an elastomeric material; e. said hollow center of said preconstructed, seamless cells containing a gas within said hollow center under pressure above that of atmospheric; f. said multiplicity of preconstructed, seamless cells having surface portions of said external cell wall surfaces, engaged with external cell wall surface portions of adjacent cells in a state whereby substantially all of the total external cell wall surface of all cells, is in engagement with surrounding portions of external cell wall surfaces of said surrounding cells; g. said multiplicity of preconstructed, seamless cells are permanently connected together at said engaged external surface portions in said engaged state to collectively provide said cellular tire insert whereby the cells of said cellular tire insert remain in said connected and said engaged state. - View Dependent Claims (3, 5, 7, 9, 11, 13)
