Incidentally, it may be a good practice to use a bench grinder and feather the ends of the Tuffys. That's been my practice, anyway, because otherwise it may happen as you say... the abrupt edge of the Tuffy can chafe its way through the inner tube.
I had covered the ends with electrical tape. I was going to smooth the ends on the next flat, but ended up changing tires instead. I do think that at least once it wasn't the end that did it, but the side edge where it overlaps (and thus is thicker). At least I saw the usual worn groove going over the actual puncture as usual.
