Just take it to a shop and see if they will mount/balance it. I do it and will tell them they will have further issues being the rim is bent, I then note it on the r/o and then they sign the receipt so I am covered. Done it plenty of times. It also depends on how badly it is bent too. if it will hold air, I will do it, if not,see ya.

For future referance, try not to buy rims that might be discontinued, if at all possible.
