Sure thing
@Cowby --- though once I get them installed I will make a brand new thread, with the same data. But for those like yourself who are anxious to know, I'll list it below in a second. But first, in case anyone cares-- I had been researching options since picking my CPO MX 75D -- actually before I even picked it up. I'd always known I wanted 21" or 22" wheels, but with Ohio roads as they are, and the weight of the OE 22s, always expected to go a different route.
After finding the price point for most 22" wheels was beyond what I wanted to spend, and still wanting just a bit more sidewall, the 21" option just made sense. And once I learned that one of my favorite tires, the
Pirelli Scorpion Verde All Season were available in correct 21" sizes, it was a no brainer for me. (Pricing was cheapest at Tire Rack for the tires, and those are already out for delivery today)
NOTE: To ensure fitment, I did make a phone call to Niche and verified the brake caliper clearance and other factors. They said they had fitted the 20" version of these same wheels, and that 21" would fit fine. I went over the list below, part number, width, offset-- and was assured it would be a good fit. With that said, here is what I bought:

Some interesting things to note:
Front wheels are same width & offset as stock 22s so the fitment will be identical
Rear wheels are same offset, 0.5" wider, so you'll have 0.25" inside/outside added aggressiveness
See prior post for tire sizes (265/40 and 275/40) -- the fronts are same width, rears are 10mm less
Overall the lower rear width will reduce rear grip slightly, but doubtful that will make ANY noticeable difference. As a matter of fact, the load rating and tread wear on these new 21" tires is higher in both cases. They are LRR which should help, too (low rolling resistance). I suspect no change in ride quality in any perceivable fashion, but will definitely report back in the weeks to come.
Only item that I did not order online are the tire pressure monitors (TPMS) as those are a stock item at the local Tesla store for the same price (or cheaper) than most online outfits. Tires should arrive today, hub centric rings and locks later this week-- wheels, with any luck, sometime next week. If all goes to plan the wheels/tires/TPMS will get mounted/installed by the end of next week, with photos forthcoming there-after!
If anyone has any other questions let me know. I'm excited to see how these drive. I don't know how easily I'll be able to collect wh/mi data that I can argue is directly comparable versus just "similar" conditions--- but given my current 405 wh/mi average on 22s for the past 1,400 miles -- I really hope to see that drop to 380'ish (fingers crossed) ... more data as it unfolds!
