VISUAL GUIDE FOR INSPECTION AND CLASSIFICATION OF TIRES
2-51. RETREAD CONDITIONS (Con't).
f. Excessive Buffing. When the tire below and on the left lost its tread, it became apparent that the
failure was caused by inadequate bonding of the new tread because the retreader buffed deeply into the
sidewall. This tire cannot be reworked because of exposed body plies.
g. Tire Slightly Overbuffed. The tire below and on the right was buffed slightly into the sidewall
fabric. In most cases this is only a minor cosmetic deficiency. However, make sure that the overbuffed
area does not extend to the body plies.
h. Compressed Beads. This condition, shown below on the left, may be permanent or temporary. If
the beads deformed in the retreading (molding) process, it is permanent; if it is the result of tires being
piled on top of each other after curing, it is temporary. If the tire is extremely difficult to mount, assume it
was compressed in the mold and should be returned to the retreader.
i. Cracks in Rib Groove. These cracks, shown above and on the right, occurred on a new retread
tire immediately after inflation. The tire was too large for the mold, or over cured and should be returned
to the retreader.
