Update, Sherri's tires just arrived. I have everything shipped to our office. Looked at COO and they were manufactured in Canada.
Found a discussion where at least one guy believes COO for Michelins is a factor.

I find that hard to believe, as I would assume that all the manufacturing equipment is the same from one Country to another, that the same compounds are used, and that the process is mostly automated, eliminating human error. But, apparently I am not the only one having difficulty finding round tires lately.
