PROBLEM TO BE SOLVED: To provide a tire stacked structure capable of obtaining high rigidity by eliminating clearances in cavity parts of tires. SOLUTION: Preload is applied in the stacked direction of waste tires 2 in the tire stacked structure formed by stuffing the cylindrical interior of the stacked waste tires 2 with a granular material 5. As a result, the clearances in the cavity parts 4 of the waste tires 2 and mutual cavities of the granular material when stuffed with the granular material 5 are thereby eliminated to make the interior of the cavity parts 4 solid, and the tire stacked structure can be utilized as an improved body of extremely high rigidity. If unitization is carried out in a state of prestressing the stacked direction of the waste tires 2, unitization can be carried out beforehand outside the construction field to obtain an improved body of high quality controlled in quality by combining waste tires of the same size, for instance. Further, transportation and installation during construction are facilitated by unitization. Further, if unitization is carried out in the state of prestressing the stacked direction of the waste tires, the tire stacked structure is applicable as an independent structure such as a retaining wall or a structure (bridge pier) foundation.
