Used tires are sorted on-site to separate those which are still good from those that are scrap. At the site, the sidewalls are separated from each scrap tire and the remaining tire portion is slit transversely and laid flat, stacked one atop the other. The stack is transported by vehicle from the site to a central processing facility that shears the tire portions to a uniform width and thickness. The uniformly dimensioned tire portions are then connected into strips by male/female dovetail cuts. Two strips are bonded together at their flat inner tire sides to form a two-ply tread strip. The two-ply tread strips are then used in construction, building component manufacture, fencing or landscaping; the two-ply treads are more flexible then lumber. The sidewalls are used as landfill or grounds cover in landscaping.
