This is exactly the article I was referring to! Before anyone jumps to conclusion, there is one very important fact that is not addressed, to my knowledge, in this article, and that is what amount of pressure it takes too break the bead when dismounting a tire. Been there on every occasion that I had a tire mounted/unmounted and believe me when I say it takes as much or more effort of the tire machine or hand bead breaker to break the bead on a cycle or car tire. Not scientific evidence by any means but a visual of the bead breaking operation is worth a thousand words. When the tire is aired up and you have that distinctive "pop" you know dam well the bead is seated. This is JMHO. Been doing Dark Siding for so long its the norm for me. Never, in almost 100,000K miles of DS riding, have I had a issue with bead separation.
