My bad. I clicked this link because I just did a ton of research on 19" tires for my Model S cars including the Michelin offerings and settled on the "perfect tire" for my needs after compiling all of this. I thought maybe I could offer some independent insight to someone on a similar path and just found your wording a bit... odd. I wanted to make sure I wasn't going to waste my time typing up a lot of what I felt was useful info for someone who didn't want it. Now, after clarification, I still have no idea if you are actually seeking information and help based on your attitude so I'll just politely bow out of this thread and wish you the best of luck on your search for info... or not. Whatever it is your attempting to do here.
