I recently had to fit a tubeless motorcycle tire onto a spoked rim that required a tube. The sidewall of this tire was so stiff that I just couldn't get enough tire to rim clearance to put the valve stem through this rim and I have mounted very long motorcycle tires. This little tool is the only thing that ultimately made this job possible. With most tire and tube combos I've ever fitted this tool would be considered a pure luxury, but in this case it has become a necessity. A very useful tool for your business.
