The Bandag Retread Process
Modern retreading is a lesson in simplicity. In 10 expedient stages, the process is complete, and your fleet is safely back on the road.
Sullivan Tire assigns a unique barcode to every casing so it can be tracked in real time, making retreading more efficient. Here’s how the rest of the process unfolds.
Step 1: Initial InspectionTrained Bandag specialists perform a visual, hands-on inspection from bead to bead inside and out. This is done to find and mark all visible injuries.
Step 2: Electrical InspectionActual damage can be closely evaluated by looking “through-the-tire” in the crown and sidewall areas that may not be visible to the naked eye.
Step 3: ShearographyThis determines conditions within the casing, subjecting it to a vacuum while lasers measure surface anomalies. An animated visual of the anomalies determines casing condition.
Step 4: BuffingAt this stage, the casing is inflated to its operational shape. The process removes the worn tread surface, trues up the roundness and prepares the surface for a new tread.
Step 5: RepairAny damaged material identified during initial inspection is removed and repairs are made, essentially returning the casing to a useful life.
Step 6: Applying Cushion
An uncured bonding layer is extruded onto the prepared casing surface and all skives are filled. The casing is ready for a new tread.
