Abstract: A retaining wall is formed from a plurality of segmented automobile tires. The sidewall segments are disposed horizontally to form a row with the ends of adjacent segments overlapping. Openings near the respective ends are aligned to cooperate with one another. A plurality of rows are formed and the openings are vertically aligned to form a height of the wall. Rods are disposed through the aligned openings to interconnect the rows. Tread segments of the tires are connected to the sidewall segments with the tread segments extending outwardly. The tread segments form support sections and may be connected to pilings to provide additional support for the wall.
