This is just another thread with a difference of opinion. The OP and anyone with a similar problem will have to decide for himself, based on the specifics of his tire, and weighing the various opinions offered here. In doing that he can consider the number of opinions, how they're explained, and the credibility of those posting.
In deciding, one should consider the likelihood of failure, the amount of warning one might expect, and the likely consequences of a failure. In some cases where something is dicey, one might decide to use it with restrictions such as frequent inspection for changes or, for a tire, restrict it to the rear wheel and around town riding.
There's no point posting more since it would boil down to "I'm right, you're wrong" because there's nothing more to say.
