I don't know whether Tesla would consider the wheels to be a warranty item, but Luke at the service center said it was a good investment to get the road hazard warranty because of the cracked 21" wheel issue, so I doubt he would say that if Tesla would have covered it anyway. I know he made the claim through the road hazard warranty program for me. And Spleen, I know the 21's are not the smarter choice as far as curbing, reliability, and faster tire and costlier tire replacements, but damn they look good!! LOL
