Retread Tire Processing Method

In the process of retreading a used tire, the worn-out tread rubber is removed, and any nail holes or damaged areas are carefully repaired. Afterward, a new layer of vulcanized rubber is applied, and the tire is heat-treated either in a mold or chamber, depending on the processing method.

  • Hot-Cap (Mold Cure)

    This method involves retreading up to the shoulder of the tire. It provides a clean appearance and performs well in harsh conditions such as construction sites or rough roads.

  • Cold-Cap (Pre-Cured)

    This method only retreads the worn-out section in contact with the road, making it suitable for use in well-maintained conditions, such as paved roads.
