You didn't mention your front axle weight, If you don't have a heavy front axle the rims are the same. a factory front axle rated at 18000lb or higher will have a heavier rated rim which is stamped on it and will also have smaller diameter holes in the rim which adds strength which should not be moved from the front axle.
Please allow me to summarize. The answer to your question is YES and NO and MAYBE. please post pictures of what you have for answers specific to your application.
That there looks sweet. Probably too much for me LOL. Noticed the deck on the rear frame. That can't just be for the show truck runabout up there.
