No rim damage whatsoever. I'm pretty cautious with them around curbs though as I have curbed wheels before and find it highly unpleasant on par with hearing fingernails on a chalkboard.
I have had my rear tires replaced but not because they wore out. At one point I got a strange shimmy I could feel only on the newest, smoothest pavement on the highway at highway speeds. The SvC checked them while in for having other delivery niggles corrected and found that they failed their road force balancing so they replaced them.
I drive in the "Low" suspension setting all the time and realize this may lead to premature tire wear (especially in the rear) so I will keep an eye on that. But since the rear tires have already been replaced I haven't seen any yet.
Oh yeah, I have just over 5000 miles currently. The tires were swapped at ~2500 miles.
Cheers!
