Bandag Retreading

Bandag Tire Repair and Retread System

The Bandag Tire Repair and Retread process begins by determining which tires are ready for retreading. We are dedicated to making sure the foundation of the tire meets all standards to ensure reliable, long lasting and trouble free performance of your Bandag retreaded tires.

Quality you can count on starts with the Bandag Process.

Bandag Process

Initial Inspection - A 396 Spreader

A visual, hands-on inspection from bead to bead, inside and out, is done to find and mark all visible defects.

Bandag Process

Initial Inspection - B NDT IIB

An electronic inspection designed to find all “throughthe- tire” penetrations in the crown and sidewall areas.

Bandag Process

Initial Inspection - C 7400 Shearography

An inspection to determine the conditions within the casing. The casing is subjected to a vacuum while lasers measure surface anomalies (ie: expanding pockets of air). An animated visual of the anomalies aids in determining the casing’s condition. At the end of the initial inspection, information like casing condition, casing age and fleet specifications are considered to determine if the tire can be retreaded.

Bandag Process

Buffing 8400 buffer

The casing is inflated to operational pressure. The process removes the worn tread surface, trues up the roundness and prepares the surface for a new tread.

Bandag Process

Repair

Removing all injuries identified during Initial Inspection and replacing the material with structurally sound materials that will return the casing to a useful life.

Bandag Process

Applying Cushion 6400 Extruder

In a one-step process, an uncured bonding layer is extruded onto the prepared casing surface, all skives are filled, and the shoulders are stripped. The casing is now ready for its new tread.

Bandag Process

Building 5400 OSM Builder

Automatically applies a new tread so it is straight, centered on the casing, and the end splices match.

Bandag Process

Enveloping 1210 Enveloper

Encases the uncured, built tire in an elastic envelope in preparation for curing.

Bandag Process

Curing 4150 Chamber

An autoclave-type device that applies heat and pressure, and over time, causes the the bonding layer in the built tire to cure; permanently adhering the new tread to the prepared casing.
