19" Rotor wheels- is anything wrong with them?

[Quattrofish]

I just bought a 2014 S4 that came with the 19" 5-spoke "Rotor" wheels in titanium finish. Love the look of them, but I checked out the classified forum here on Audizine and was amazed by the number of sets for sale. It made me wonder if there are issues with these wheels that are causing people to unload them, or are they just popular and thus marketable?

I'd like to swap the Conti3s currently on them for something that won't kill me if I'm caught out in some snow (I have a 1997 Suburban that I drive when it gets sloppy), but if the Rotors aren't good, strong wheels I'll find something else.

Thanks for any input.

they are fine if a bit heavy for the size. I'm love the look but selling to get lighter weight wheels because they are marketable. Stock rotors are like 28lbs. I'm going to measure tomorrow with tire.
