using tubes as wheel spacers?

Well, it was a little bit of both, I did want to run this by you guys but I can never turn down a good laugh

It turned out that the bolts on the hub don't line up with the rims I wanted to use so to make it work I would have to remove some of the ribs cast in the back of the hub and drill new holes for the new bolt pattern
In the end, I decided to just buy new tires and put those on the rims that were on there

But I do appreciate everyone's input
