We used to have a small shop and had to work on combines while the big shop was being built. Someone welded the wheel center for a combine in a truck rim. They would swap the tires and drive the combine right in. Swapping the tires was a pain but it beat working outside in the winter.
Before you weld on any rims, be sure to watch Bridgestone's video on pyrolisis. You can find it on youtube.
