Abstract
Old, spent or worn tires are recycled by removing non-rubber components such as belts, beads, and fabric, and grinding the remaining cured rubber into fine sized particles. The ground particles generally replace equivalent amounts of rubber and additives in various tire formulated components such as tire treads. Good physical properties of the end product are retained.
