Abstract:
A tire, comprising:a) a casing defining a hollow interior;b) said casing having an initial inside diameter and an expanded inside diameter;c) a fill disposed in the interior of said casing, said fill including a first layer and a second layer;d) said first layer having an initial outside diameter, said initial outside diameter being substantially the same as said initial inside diameter of said casing for contacting said casing, and said first layer having an expanded inside diameter and an expanded outside diameter;e) said first layer having first and second free ends, and said first free end being disposed substantially adjacent said second free end;f) said second layer being disposed substantially adjacent said first layer;g) said second layer having first and second free ends, and said first free end being disposed substantially adjacent said second free end;h) each said first and second free ends of said first and second layers being sufficiently freely movable toward and away from each other so that, when said casing assumes said expanded inside diameter, said first free end of said first layer moves freely away from said second free end of said first layer and defines a first gap therebetween, said first layer assumes its expanded outside diameter, and said first gap being sufficiently large so that said first layer is sufficiently large to contact said casing, and said first free end of said second layer moves freely away from said second free end of said second layer and defines a second gap therebetween, said second gap being sufficiently large so that said second layer is sufficiently large to contact said first layer; andi) when said casing assumes said expanded inside diameter, said casing is substantially free of space between said first layer and said casing, and said first layer and said second layer are substantially free of space therebetween.
