I had a Goodyear, a number of years ago, have the cross ply come
'unbonded' within the carcass.  It happened while the car was loaded on
the trailer.....went to roll the car off the trailer and it didn't want
to move.....one of the front tires had to overcome about a 2 inch hump
where the ply had unbonded and was attempting to form a pretzel in the
surface of the tire....strangest thing I have ever seen.

I had some Goodyears do this a few years ago.  They replaced them, but
told me that their engineers would swear that they would be fine.  But
the GY dealer agreed with me that the engineers butts weren't on the
line like mine was with those tires.

Race tire tread is put together with multiple pieces.  You can see the
seams on the surface of a new tire.  If they don't vulcanize all
together, this is what can happen.  This is why the GY tires are
supposed to be mounted a certain way for their first run, to complete
the bonding process.

I'm not a tire engineer, but I did stay at a Holiday Inn Express last
week....
