Retreading or recapping a previously worn tire through a remanufacturing process is designed to extend the tire's useful service life.
Retreading starts with a safety inspection of the tire. The old tread is then buffed away, and a new rubber tread is applied to the bare casing using specialized machinery.
Retreads are significantly cheaper than new tires. As a result, they are widely used in large-scale operations such as trucking, busing, and commercial aviation. They are also the most environmentally friendly way of recycling used tires.After buffing off the old tread, the process of retreading requires that there be a coating with another compound like rubber to allow the new tread to adhere to the used tire casing.
