peete17,
Kevin is right about the original rim size of just 16" x 4" wide. You can however bolt up some later 16" x 4.5" wide rims (used on 1/2 Tons up through 1955) if you can find them with some still round tires as a temporary solution to putting some rolling stock under it just to get onto the trailer and home.
This is all assuming (yeah I know what that can mean - lol) that you are just looking for a temporary solution to get it home.
