Does anyone have an avenue on getting a replacement rim for my 2012 boat trailer?

Last weekend on the way home from a fishing trip, I pulled out of a gas station parking lot and blew a tire.

Get the tire off and the cause wasn't the tire.... 3/4 of the backside of the rim was blown apart.

I'm thinking I hit a hole where my tire fell into the hole while the rim bounced off the concrete.

Thanks,

FF
