Tire retreading begins with precise buffing of the old tire casing to remove worn tread, followed by thorough inspection and application of bonding agents to prepare for new rubber. The core components then include either pre-cured tread rubber with existing patterns or uncured rubber that gets molded during the curing process, which takes place in specialized chambers that apply carefully controlled heat and pressure. Finally, sophisticated quality control equipment including x-ray machines and pressure testers ensures the retreaded tire meets safety standards before returning to service.
