With regard to the peer comment by Rolf:

Thank you for pointing out that a slip of my finger missed the upper case "P" for Profil (and, perhaps, a couple of hyphens). If it were possible, I would have changed it, but, as you know, an answer, once given, may neither be edited, nor corrected.

As to the placement of what I posted as "Just for reference", that is precisely what it is - reference information to support the answer immediately above it with various uses of the term bead in relation to tyres (or tires).

I doubt very much whether this will annoy the asker, as it will save looking for it somewhere else.

My sole aim here is to provide suggestions and information that may be, I quote, "most helpful" to the asker, no more and no less.
