Yes I know they have an impact on max range but didn't know going from 19" to 21" wheels would have a 40mi. impact; either way, it's all good...350 mi. max range is far better than 250 mi. max range. Besides, yes I agree the 21" arachnid wheels, although they're not my favorite design, still look far better than the 19" standard wheels for the Model S. Too bad Tesla doesn't offer 2+ wheel designs for each size. I bet many people just get the std wheels and then upgrade them to whatever they want after. I'll just stick with the arachnids I think. A couple of my favorite wheel designs are the 21" Porsche Turbo wheels I had on my Porsche Macan Turbo and the 22" Jaguar wheels with carbon fiber on my Jaguar I-Pace.
