A Second Life and Beyond

Earthmoving tires

Application is an important consideration in the retreading process, since tires used in off-road applications can go through a wide variety of operating conditions, even on the same machine.
To determine a tire's retreadability, the casing is put through a gamut of tests, including shearography, where the casing is examined from bead to bead.

Manage the environment
Since application plays a vital role in casing health, it's also important to manage site conditions.

"We find a lot of damage can be done to a tire that renders the original tire out of service, as well as the casing and the ability to retread it," says Tolman. "Keep service roads and working areas clean. If you have areas where you're running over a lot of debris, you can cause unnecessary damage to the tire, the tread and the casing."

Consider haul roads and other jobsite conditions. Haul roads should be of the proper length to allow the tire to cool down as it's designed. When creating turns to navigate sites, make sure you have the appropriate bank so the load weight doesn't shift unexpectedly on the truck, which then shifts weight on the tire and can cause damage.

"If you bank roads properly, and loads stay as they should as they travel throughout the route, the tire and the vehicle are kept in the best condition possible so the casing can be reused," says Tolman.

As more contractors have tried retreading, they have discovered - when done properly and through a qualified retreader - they can have a positive experience with a retread product. "By using a premium, good quality casing, coupled with a good quality retreading process, they can use a retread product with great success in their operation," says Tolman.
