The bike in the pix of the first post, is certainly not a garage queen and looks well travelled. For all we know, that rear tyre may have been the only suitable size that was readily available at that point in time, to allow a journey to continue. Waiting for a specific tyre could be a major upset, especially if touring with a group of riders. Without all the facts, one can only speculate. I do understand that regulations differ from country to country.
