Those are the two most common tire sizes in North America. Not hard to find parts for the cycletrucks at all, the 559/406 wheel combo is easy to find tubes and tires for, they sell them at almost every store with sporting goods. I'd use one, no question. These are good for delivery people who need to keep an eye on their cargo, or have wide things that don't work well on a traditional rack.
