Seeing a lot of E60s with aftermarket wheels....

Am in the process of visualizing mods & was wonering if the blue & white propellor from stock wheels can go on 19" BBS CH. Stock wheels are 17" I think. Also, what is the fattest tire size one can put on teh BBS CH without affecting handling, rubbing etc.

TIA

 

245/40/19, 275/35/19 no rubbing

 

Do you see these e60s on the forums or on the road? I personally haven't seen any with aftermarket wheels, but I don't see many e60s to begin with.
