I thought that I would toss a couple more data points onto this thread based on some recent experience.
I took delivery of my M3P in December, and then wanting to not end up trashing the 20" wheels in DC during my commute futzed around for a long time trying to find a set of replacement wheels. Got a set of Sportline TSTs right after the 'tramp stamp' went on, so those went back, and then waited for the COVID boat from China to bring a set of 18 8.5 Silver MW03's over, which finally arrived in early July.
Based on the master tire thread from awhile back, and a few other data points, since I also drive places for work, I thought I'd fail safe and put on a set of 235/45-18 CrossClimate+'s. The noise and vibration difference from my 20" PS4's was...impressive. In a really bad way. It would have been bad enough that I would have probably gotten rid of them even on my Audi, but on the M3P...yeah. On some roads the CrossClimates set up an odd harmonic that just went through the whole car. Solidly the worst tire experience I've had in a long time, and I was pretty unimpressed with the MXM4's that came on my Model S.
I thought that maybe there was a chance that maybe the original balance had been done wrong, so I took it over to a local shop that I trust that knows Teslas and had them road force balance the wheels. That helped with a good portion of the vibration, but not much on the noise front, and after a couple of 300 mi road trips, the vibration started to creep back up too.
I got in touch with the shop, and they helped me run the claim with Michelin (I was about 1500 mi and <60 days on the CrossClimates), which I got replaced with Pilot Sport A/S 4's today (same size/aspect) for the cost of labor. So far, it's a step improvement. At least as good as the PS4's on the drive home, and I think somewhat better. I'll update once I get them broken in.
