Our local farmer's co-op tire shop has the equipment and the experienced people to deal with multi-piece rims. There are a few common sense precautions such as using a cage while inflating the tire and inspecting the pieces of the rims for rust or damage. When I started dealing with those wheels 50-something years ago, I was taught to be careful not to mix up bits and pieces of wheels that had been running together for a while. They establish a wear pattern that keeps mismatched parts from getting assembled safely, in some situations.
