1. Inspection and preparation

   A worn tire is thoroughly inspected for damage that would make it unsuitable for retreading.

The old tread is buffed off, and the casing is cleaned, repaired, and prepared for the new tread. Specialized technology like electrical and shearography inspections are used to find non-visible damage.

1. Tread application

   Precure method: A thin layer of "cushion gum" is applied, and then a pre-manufactured, vulcanized tread is wrapped around the casing.

Mold cure method: A strip of uncured rubber is applied directly to the buffed casing. This process is more similar to how new tires are made.

1. Curing

   Precure method: The tire is placed in a curing chamber where the cushion gum and tread are bonded together.

Mold cure method: The tire is placed in a mold that forms the desired tread pattern. Heat and pressure are applied to vulcanize (cure) the tread onto the casing.
