Scrap Tires: Handbook on Recycling Applications and

The scrap tire problem is fueled by the current economic variations within the U.S.-Mexico border region. Millions of used tires move from the United States to northern Mexican border states for reuse and disposal. Because of their lower cost, approximately half of all tire purchases in Mexican border cities are used tires from the United States.
