My almost free 21" wheels mounted for the first time. I'd still prefer a 20". These were nearly free after wal-mart cut me a check for scratching the insides of the lips when mounting. For the background of my quest to add these for cheap, see this thread: Cost to add a 21 wheel set....... The ride comfort is just a tiny bit worse than the 19s. No surprise. Tesla has been telling me that the reason the P85+ loaner I had was so much more compliant than my ultra stiff shake-you-teeth-out-of-their-sockets ride of my P85D is because the 21" wheels have a much softer ride due to the summer compound despite being lower profile. I called BS on that and upgraded to these(keeping my 19s of course for longer trips). Now I can go back to them and challenge them to tell my why March P85Ds are the only ones that have the largest anti sway bars. 28mm front and 23mm rear which are bigger than the ones I measured in January on P85Ds and WAY bigger than the April after Tesla dropped the + suspension. The grey compliments the dark grey of the car nicely.
