Puncture resistant tire assembly

A tire assembly for preventing depressurization of a pneumatic tire pierced by a sharp object, comprising:

• an inner tube having an outer periphery with protruding pressurizable structures integrally fashioned thereon, the pressurizable structures of a cross-sectional shape which includes a tapered tip to present a surface which minimizes exposure of the pressurizable structures to a substantially vertically piercing of said tire by such sharp object;
• and
• shape-maintaining means for maintaining the approximate shape of the pressurizable structures when said tire is under load while allowing for substantially lateral deflectability of the pressurizable structures upon contact of the same with said sharp object.

A puncture resistant tire assembly for a tire having an interior surface, comprising:

• a first tire liner having a plurality of radially inwardly projecting separator structures thereon, said first tire liner being substantially circumferentially continuous within the tire interior surface;
• and
• a second tire liner having a plurality of hollow radially outwardly projecting deflectable structures having a tapered tip to provide a deflectable structure surface that is inclined and to present load bearing surface of minimal size, the deflectable structures being mateably received by the separator structures and shapely supported thereby, the separator structures cooperating with the deflectable structures for deflection of the same upon puncture of said first tire liner by a sharp object.
