My friend has come across a number of wheels and I am asking for help.

1. He has a set of 4 BBS wheels, 16x8, 5 lug, chrome rims with grey basketweave with lugs (innies) all around rim. Two of them have 225/50zr16 and the other two don't have tires at all. Look in good shape, and if washed, would probably look excellent. The center hub is BMW Roundel, but yellowed.

2. He has a second set of 4 BBS wheels, 16x8, 5 lug, polished rims with grey basketweave with lugs (outies) all around rim. Two of them have 225/50zr16 and the other two 245/45ZR16, also in good shape, needing wash. These have the BBS center hub.

I am interested in purchasing one set from him (for my 88 M6), but he doesn't know, (and I don't either) how much to charge for them. According to him, he has been told that they fit a 6 series, but I don't know the offset, how do you measure this?

Any help appreciated,

Thanks, Pedro

PS. He also has some MBZ, other BMW, Pantera, GM wheels and tires, he is a auto detailer and is planning to sell them for one of his customer. If anybody interested, let me know and I can find out info for you.
