So you don't search the forum, you search the site/google? I'll do that next time, thanks. Also thanks to Roy, that's what I was looking for. After reading through that and the links from that, it appears that some bare rims would be the easiest. How small can you go? I found some 8" with 5 on 4.5 for $20

Maybe 10" or 12" would be better, the 8" would only give 4" from the center of the hub to the ground?
