I've been working on making my Tri-Rod street legal for Indiana. In the process, I discovered that a "convenience spare" from any ford with a 5x4.5" bolt pattern will bolt right on the hubs on my BGW. Here is a pic with a 16" rim/tire with a trim ring and a police hubcap. The skinny tires are a little goofy looking, but I like it for the price. $10 for a wheel and tire from the local junk yard. Now to go pickup a second one.
