| The challenge common in retreading radial OTR tires has always been to make casing last as long as the second tread life.
The most common failure modes of radial OTR tires are:
1. Sidewall damage.
a. Radial cracking due to fatigue.
b. Damage due to cuts and scrapes
2. Casing belt edge separation.
a. In our experience, over 50% of all worn radial casings 26.5-25 and larger have some degree of edge separation.
b. These separations are uncovered in our buffing process which follows the contour of the worn tire.
c. Left untreated, these separations will continue to grow in size and the tire will fail before the second tread is worn out.
