Could be an IPD 'R' type wheel. Like the guys have said, if it is a Volvo it will have a part number on the back as well as all the info on dimensions and offset.

Should also say, that rims can be repaired, but unless you really like them it is often cheaper to find a good used set for less than it costs to repair. I have had a few where they bend on the inner edge following a pot hole hit. We have a guy that can repair them but it costs about CDN$ 120.

Get the engine family ID off the engine block.
