Retreading

Oliver retreading steps*

1. INITIAL INSPECTION

Every casing, every detail, inspected every time – Enables trained operators to detect subtle irregularities that may indicate internal damage such as zippers

2. BUFFING

Our goal is to create top-quality tread-building through proper texturing and uniformity, ensuring the tread bonds with the casing for superior and long tread life.

3. REPAIR

Casings in need of repair are sent to our Skive and Repair station.  Here, they are repaired thoroughly and efficiently from crown to interior, so the casing leaves in a top-quality operational state for our Tread Building Station.

4. EXTRUSION

Our innovative extruder machine ensures that the uncured cushion gum rubber is placed upon the casing with uniform thickness.  The extruder machine can adjust to the width of the tire, allowing us to retread more tire per hour.

5. TREAD BUILDING

Precured tread is now applied to the casing.  The tread building machine utilizes exact casing measurements to ensure precise tread application.

6. ENVELOPING AND CURING

Before a tire is cured, it first receives a curing envelope to ensure temperature and pressure uniformity in the curing chamber.  The tire is then cured in a proprietary curing chamber to exact specifications of time, temperature and pressure, depending upon the tread selected.

7. FINAL INSPECTION

Each retread starts with a thorough inspection and ends with a thorough inspection.  No tire leaves the plant without undergoing a detailed, hands-on inspection by an expert technician.  This technician inspects the crown, beads, sidewall and interior to make sure every tire meets the high standards of quality.
