Abstract:
A cellular tire liner and air chamber system for lining the interior of a pneumatic tire, said system comprising:a. a cellular tire liner having an elastomeric cellular structure composed of a multiplicity of elastomeric cells; b. an air chamber for said interior of said pneumatic tire that is subsequently sealed and pressurized; c. when said cellular tire liner and air chamber system is lining said interior of said pneumatic tire, said cellular tire liner being interposed between the interior surface of said pneumatic tire and said air chamber; d. when said cellular tire liner and air chamber system is lining said interior of said pneumatic tire, a substantial portion of the exterior surface of said cellular tire liner that is adjacent to said air chamber forming an essentially vee shape, thereby defining a substantial portion of said air chamber in said essentially vee shape, with the widest part of said essentially vee shape furthest from the tread area of said pneumatic tire; e. when said cellular tire liner and air chamber system is lining said interior of said pneumatic tire, a multiplicity of said cellular tire liners are used in said interior to line said pneumatic tire, said multiplicity of said cellular tire liners establishing an annular interface; f. each of said cellular tire liners in said multiplicity of said cellular tire liners are individual and independent from other said cellular tire liners in said multiplicity; g. said annular interface being a ring-shaped surface forming a common boundary between said individual and independent cellular tire liners; h. when said cellular tire liner and air chamber system is lining said interior of said pneumatic tire, said annular interface extends from said air chamber to said interior surface of said pneumatic tire, in said tread area of said pneumatic tire; i. when said cellular tire liner and air chamber system is lining said interior of said pneumatic tire and said pneumatic tire is mounted onto a wheel, upon pressurization of said air chamber said, pressurized air chamber exerts a constant force on said multiplicity of said cellular tire liners and presses said multiplicity of said cellular tire liners against said interior surface of said pneumatic tire, whereby said pressurized air chamber completes the required force necessary to establish the entire load bearing capability of said pneumatic tire when said air chamber is sufficiently pressurized.
