This bubble was indeed caused by a split in the inside of the tire. Dunlop and
the tire installer (America's Tire, which handled the situation poorly) said
that such a split could be caused by a manufacturing defect or by a
significant road impact. They both claimed that the interior of the tire was
consistent with the latter (I sent a Dunlop rep a digital photo), though I
found it hard to believe I had hit anything hard or sharp enough to do that.
That was three years ago, before the Firestone/Explorer mess. Perhaps the
Audi/Dunlop replacements were after...
