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. Besides, the inner tire is produced first independently and then put in the tire embodiment, so the tire embodiment is free of easy deterioration and aging as a result of secondary processing of the tire embodiment.
