i find it hard to believe a simple plug could cause a tire to "come apart" or fail due to extra heat. only cord damage could do that and a patch won't fix that either.
btw do you have a link describing this extra heat build up that causes a tire to come apart.

but a foreign body "on" the inside of the tire won't? i.e. a patch

There is nothing rubbing against a patch on the inside of the tire that would generate heat. Almost all heat in a tire is generated by friction, the flexing of the tire. This is why under-inflated tires are dangerous. When they have low pressure, they flex more. A plug stuck in from the outside is a foreign body in the carcass...the extra friction in that area can cause more heat in that area...get enough heat and say good bye. Heat causes cord damage...a la Firestone a few years ago. Same internal friction is demonstrated by taking a metal bar and bending it back and forth with your hands...it will get hot at the bending point from the internal friction. All tire companies say not to plug a tire from the outside....thats all tire companies...maybe they know something about tires.....
