ABSTRACT:
The ground anchored post is made exclusively from the steel-belted treads and metallic wire rings of reclaimed, used, pneumatic tires. Each used tire is cut with a shearing tool to remove therefrom the rubber side walls thereof. A selected number of treads are then compressed flatly against one another, while a plurality of wire rings engage by their hollow the compressed pack of treads. The total number of treads selected is a function of the thickness of each tread and of the diameter of the tires, whereby the number of treads is high enough to provide taut, friction-fit engagement of the wire rings around the pack of treads. The taut engagement of wire rings around the pack of treads positively prevents the treads from engaging in sliding displacement relative to one another.
