ABSTRACT:
A retaining wall system (10) is defined which includes a plurality of tires arranged in a plurality of courses (14). The tires can be offset within the wall and can be cut in various ways to advantageously improve the strength of the wall. In addition, reinforcing (25, 30, 32) formed from tires or conveyor belts can be associated with the wall system to improve the structural stability of the wall.
