just pondering getting a set of winter wheels, and wondering if 17" rims fit on the 550i.

 

Yaa ... but check & make sure http://www.realoem.com/bmw/showparts.do?mo...hg=36&fg=15

 

Yes, the style 116 was the factory OEM wheel for 545's and 550's (pre-LCI) in the US for cars without the Sports Package. Had them on my old 545... I actually liked the wheel and wish they made them in an 18" or 19" size.
