VISUAL GUIDE FOR INSPECTION AND CLASSIFICATION OF TIRES
2-51. RETREAD CONDITIONS.
a. Open Tread Splice. This type of defect is peculiar to retreads and is a gap between the tread
joint. Tread splices are normal with pre-cured, top-cap retreads but most retreaders will butt the ends up
tightly and evenly so the gap isn't that evident. It's a result of poor retread workmanship as the tread was
cut to short when applied top the casing. In most cases this will not cause any problems unless the crack
goes deeper than the tread rubber, at any location. But even if the crack does not go deeper than the tread
rubber, but the gap is obviously to big, as with the example, it should be returned to the retreader for
correction and the tire classified CRC F until fixed.
b. Off Center Tread/Mold Misalignment. Off center tread is one of the most common defects
produced by careless retreader. It is caused by improper alignment of the retread mold. In most cases the
tire is probably marginal. Nevertheless, it should be returned to the retreader for adjustment under terms of
