Tire has a casing defining a hollow interior, a fill disposed in the interior of the casing, and the fill including at least one layer having an initial diameter substantially the same as the initial diameter of the casing. The fill layer includes an expansion joint. When the casing expands the expansion joint expands and causes the first layer to substantially continuously contact the casing. The expansion joint may be configured so that the layer(s) of the fill substantially continuously contact each other and the casing, respectively, as the casing expands. The expansion joint may be engineered to produce a gap extending between first and second free ends of the layer(s). Or the gaps may be selected so that the first and second ends of the respective layers continuously remain at least partially in contact with each other before, during, and after expansion is completed; i.e., when the casing is at maximum expansion.
