Tire re treaders, also sometimes known as a recap is the effective utilization of a previously worn tire which has gone through a remanufacturing process designed to extend its useful service life. Tire retreading starts with a safety inspection of the tire. The old tread is buffed away, and a new rubber tread is applied to the bare casing using specialized machinery. Tire retreading is significantly cheaper than new tires. Tire retreading is widely done in large-scale operations such as trucking, busing and commercial aviation. Tire retreading is said to be environmentally friendly. There are two main processes used for retreading commercial vehicle tires - hot cure and cold cure. A tire can be retreaded up to 10 times.
