Awaiting delivery of black,loaded,GCSRT8 and I have already found the forum both fascinating and very informative.Because I live in the frozen north (Saskatchewan) I always have dedicated winter wheels and tires.I am using Blizzak LM22xl (255/55 18) on my X5 and they have been excellent.There seems to be a dearth of aftermarket wheels for GCSRT8.I obtained the OE specs from the posting a couple of days ago(front 20x9,5x127 offset 34.75 mm,rear 20x10,5x127,offset 50 mm) and I need to know if 18" wheels can be used for winter rubber,if they will clear the Brembos,and if so what is the optimal tire size and wheel width and offset(s).If not,what 20" wheels and winter tires are available?This is my first posting and I apologize for its length.eyedoc

Do a search on this board. Someone just put some 18's on his, and he's got pics along with specs on the wheels he bought.

Thanks Alex.I just saw the posting by the member from Montreal with his Blizzak LM 25's.His rims look quite good and I will investigate further.
