Why not take one to your TN dot and ask them if its an ok rim? Or a lessor evil is a trailer dealership.

I really could care less if you use them but ive seen many jacked passenger car rims used with the "proper" tires that were tore up, many trailers get in a decent bind backing up and I myself have bent real trailer rims and broke shackles over time.

Good luck, whatever you do.
