Sorry to have to report a difference in experience. We usually have a 4 inch overlap for the big wheel, plus a minus just a little bit for sizes more or less than a 52 inch wheel, which was the most popular size in the 1880s. If you have 10 inches of overlap, I would think is would be impossible to compress that much rubber; however, if you are using some of the plastic tubing, it might work. Gook luck and let me know how it works, especially the kind of hard rubber you are using. Check the Wheelmen Bulletin No. 4.
