I hope this isn't too far off topic. I found this caster wheel that this company is using for wheelchairs built in "low income" countries.

They told me the wheels they use can be 4 or 5" in diameter and are about 4" wide. Only about the center third of the wheel is supported by the hub, the outer section is fairly flexible to conform as it rolls over uneven surfaces. To get a look at it, check out this youtube video. They show the wheel up close at about
