I am finalizing the purchase of a 330i with sport package (18" run flats). I currently have an E46 325i with one season on a set of great Hakkapeliittas. I'd like to use the E46 rims and tires on the new E90. Can I? I've checked at TireRack and at BavAuto and none seem to offer a steel wheel. And, there seems to be some conflicting info around using my Hakkapeliitta 205/55-16.
