slybry, if they don't work, put them up for sale.
You can get an inexpensive set of after-market alloys with excellent tires at a place like Tirerack and there's also a sponsor on this site, 1010tires.com
I've purchased from Tirerack before, although it was not for the E92. It was for my Acura and price and service, even with duty, shipping, etc. was a very good value IMO. Got my wheels quickly too.
Lots and lots of people with E90's on the bimmer forums buy the (inexpensive) EDIT Rial Salerno after-market rims + winter tires combo from Tirerack, and are happy with them (I did not get the Tirerack combo for my E92 because I had my eye on a particular set of OEM wheels so got those instead)
