How to maximize truck tire retread performance
Truck tire users base retread tire performance on tread wear. When the tire body and tread work together for the life of the tread - that is, until the tread wear bars come into view or the tires are removed for retreading - the end user is satisfied.
Most retreaded truck tires wear out their applied treads. But road hazards, poor tire maintenance, misapplications and other factors can greatly affect both retreaded and new tire casings.
Casing selection is the first of many steps needed to maximize truck tire retread performance. Casing inspection is the second, and it is an ongoing step.
During 1999, truck tire retreaders in the United States produced an estimated 18 million retreaded truck tires.
However, in order to process 18 million truck tires for retreading, 24 million casings had to be inspected, probed, classified, repaired and processed.
In other words, 25% of all used casings are rejected, discarded or returned to customers.
The average reject rate of 25% on incoming truck casings for retreading is typical for most U.S. retread plants.
Casing inspection and rejection of non-retreadable tires is generally accepted as the first line of defense in …
