VISUAL GUIDE FOR INSPECTION AND CLASSIFICATION OF TIRES
(Con't)
2-49. TREAD CROWN CONDITIONS (Con't).
e. Plies Worn Through. This tire, shown below and to the left, has been used too long and is
destroyed beyond repair. The wear has progressed into the cord body. Correct classification is CRC H.
f. Uneven Wear. This condition, shown below and to the right, was caused by front end
misalignment. There are still traces of tread visible and the tire can be retreaded. Correct classification is
CRC F.
g. Excessive Tire Wear. The tire below and to the left has been worn smooth and is a borderline
case for the classification inspector. It was correctly classified CRC F and should be sent to the retreader
who will attempt to buff it, without biting into the cord plies. If this operation is successful the tire can be
retreaded without problem. Since the classification inspector can not see how deeply the wear extends, it
would be better to let the retreader try to save the tire rather than to discard it.
h. Premature Removal. Less than 50 percent of the tread has been worn on the tire shown below
and to the right. Instead of sending the tire to the retreader as CRC F, the inspector should have classified
it as CRC B and returned it to the user.
