Abstract: 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.

Abstract: A structural improvement of a solid tire is made up of a tire embodiment, an inner tire including a bottom layer , a middle layer and an upper layer. The bottom layer is a flat-topped curve-bottomed continual slab, the middle layer having an approximately rectangular cross section with top and bottom side thereof provided with axially parallel grooves and the right and left side defined in a smoothly curved surface. The upper layer is approximately in the same shape as the bottom layer but is additionally equipped with a humpbacked portion right on top of the curve-bottomed area. In assembly, the bottom layer is placed at the bottom of the tire embodiment and the middle layer is positioned next on top of the bottom layer, the upper layer is lastly placed on top of the middle layer. Such a structure makes the solid tire have a better buffer effect and lighter weight in use and the inner tire assembly can also be recycled for use after the tire embodiment is worn out.

Abstract: A lightweight, filler core tire construction for automotive and other vehicles, having a flexible composite outer layer structure and an inner flexible honeycomb core with a radial relief and said honeycomb is bonded to said outer layer, eliminating thus fully or partially pressurized air from the tire and increasing the safety of driving, damage resistance, and minimizing servicing of the tire. The structures are preferably made of a polyurethane polymer and various fibers and do not require a split rim for mounting and dismounting said tire.

Abstract: The preferred embodiment is directed to a pneumatic tire having a plurality of layers of high density foam rubber formed therein and methods of manufacturing and installing the layers therein. The preferred method of forming the layers of fill to be inserted in the pneumatic tire casing includes the following steps. Forming an elongated strip of elastomeric material of a size sufficient to form at least two concentric layers in a predetermined size casing of a pneumatic tire at a manufacturing site. At least one dimension of the elongated strip is the same as at least one dimension of the two concentric layers when inserted in the casing. Formulating data sheet having information from which the elongated strips can be cut to form the at least two layers for at least one predetermined condition. Transporting the elongated strip of the elastomeric material and the data sheet to an installation site remote from the manufacturing site.
