Why Retread? top
 |
For most fleets, tyres represent the largest item in their operating budget, right after labour and fuel costs. |
|
The lowest possible cost per mile is achieved with a good tyre management program that includes the use of quality retreads. |
|
Retreads are not only cost effective but also dependable, reliable and safe. They are used by truckers with scheduled delivery times, small package delivery companies with guaranteed service times, on commercial and military jets and most school bus operations. |
|
Today, the most successful retreaders are those with the highest quality products, delivering the best possible return on investments to the fleets. Because of the competitive nature of the retreading industry truckers can expect to see continuous improvement in quality, durability and reliability as major retread suppliers such as Bandag annually invest millions of dollars in research and development. |

| The Retreading Process |

|
| Initial Inspection | ||
Casings are thoroughly inspected to ensure they meet our high retreading standards. Our inspectors look for every cut, bruise, and puncture, as well as other damage to the tyre body. Repairs are made using strong, flexible Bandag repair materials. |
|
|
| Scanning | ||
After our initial inspection the casings are scanned ultrasonically to identify and damage that may be hidden from the naked eye. This is done using the latest in technological innovations, the NDI ( Non-Destructive Inspection ) Tyre Casing Analyser. |
|
|
| Buffing | ||
Once the casings have been scanned they are then buffed to remove the old, worn tread design. The Buffer works like a lathe as the tyre is buffered, truing the inflated casing with utmost precision. This ensures a smoother running tyre, which serves to reduce vehicle maintenance. |
|
|
| Skiving | ||
| Damaged ply and rubber material is removed while a repair is being made. |
|
|
| Repairs | ||
Once the Skiving process is completed, the casings are repaired to meet Al Dobowi Limited's high standards. Nail hole injuries, crown injuries and sidewall injuries are repair and many others are routinely repaired. This is done using specialist Bandag repair materials that have been designed specifically with today's new generation tyres in mind. |
|
|
| Filling | ||
| The skived area is then filled with repair gum using the repair gum extruder. |
|
|
| Tread Preparation | ||
| The tread rubber is then laminated with the cushion/bonding gum and is then cut to the required length to suit the circumference of the buffed tyre casing. |
|
|
| Building | ||
Once the tread has been prepared, Cushion gum ( the adhesive layer ) is applied to the back of the Bandag tread rubber. The tread rubber and cushion gum are then applied to the casing while the tyre is inflated to its normal running configuration. The cushion gum bonds the tough Bandag tread rubber to the casing and this bond becomes one of the strongest parts of the tyre. |
|
|
| Enveloping | ||
| The tyre is then encased in a rubber enclosure which provides equal pressure on all external surfaces. |
|
|
| Curing | ||
| This process allows the tread rubber to bond with the casing and is done at a fixed temperature and for a fixed period of time. |
|
|
| Final Inspection | ||
Every tyre produced by Al Dobowi is inspected thoroughly before it leaves our premises. In keeping with our philosophy of 'safety first' we ultrasonically scan each tyre in the final inspection ( the only retreader in the region to do so! ). The last place we want to discover a problem is after the tyre is in service. We are sure you would agree. |
