Without knowing if the wheel is damage it's hard to say. If it is, I would utilize the two front stlye 214s you picked up and buy matching pair of DWS06 tires. Not sure where you get your tires from but TireRack has DWS06 275s for about $250/each. If the OE wheel is still good, I would still get two matching new DWS06 tires. You can always sell one tire on the open market to recoup some money.

This happened to me on my E83 X3. Hit a curb, tire blew out. Wheel was still good, so I just had two fresh DWS06 tires installed. Granted they were 245 or 255 (I cant remember), not the bigger 275s.
