  • The Trouble with Tires Recycling Today

    Aug 04, 2001· Tires are built to last, as some are now guaranteed up to 100,000 miles. That in itself is a saving of resources, as tires made several decades ago would rarely last beyond the 20,000mile mark. Still, tire recyclers are faced with the feat of taking a seemingly indestructible product and breaking it down – sometimes into its basic elements.
