Alloy Wheel Repairs - The FIAT Forum
I know you can repair a curbed alloy by floating it down into an electrolysis bath or something so a small industry of alloy repairs does exist, but a structurally buckled one, personally I'd never be convinced it's stable under cornering or braking even if you can get it done.
If it did let go at a later date, the insurance may not pay out too.
