They are actually remarkably light weight. BMW made the profile of the spokes surprisingly thin and very flat on the back side. I wouldn't guess the wheel and tire combo is much over 35 lbs. total. I don't believe I am likely to gain much with wheel discs, but obviously I am going to try. Fairing the rear wheels however is another story. Probably lots of cleanup possible there.

I'll be removing them again soon and will check.
