Thanks for clarifyinng @Qbenjamin
Bottom line: you're using 20" x 8.5" wide front-sized wheels (35mm offset) with the 265s on all four corners.
I've ordered four 265s tires and will be trying them on the stock rear 20" x 9.5" wide wheels that have a 40mm offset and putting them on the front of the MX to see what kind of rubbing, if any, I'll get. I'm expecting some rubbing when the steering is all the way to one side but that should be ok for me. The additional 5mm offset brings the wheel closer to the center of the car, but the wheel is 0.5" wider also, so it's expected to be close to a wash (hopefully). This experiment will tell for sure. When I rotate the tires, my front 8.5" wheels will spend some time on the rear corners of the car.
Will report back here once installed. Luckily, Wheelworks is willing to install them (not all places will, citing "it's supposed to stay staggered" kind of gibberish).
Hopefully this experiment will help others in the future who might consider trying the same with the stock wheels. Thanks all.

Ok, so I've tried moving the rear wheels (9.5"w x 20" with 40mm offset) from the rear to the front of the car and at first they appeared to fit and even the mechanic thought it'd work, but in actuality, they WON'T quite fit. The wheels mounted fine and actually spun enough that we thought it'd work, but upon further inspection, there's a very slight bit of metal to metal contact between the top of one suspension part and the inside "tub" of the wheel. See red arrow in the picture. The mechanic's flashlight unfortunately washed out the contrast of the spot where the metal scraped so it's hard to see the actual part that rubbed, but it's where the arrow is pointing at, and it was a very small amount. The rub was approx 1mm wide, and interestingly, not continuous (not the whole washed out part of the picture).
Now, having said that, I currently believe that with a small grinding mod to the part rubbing the wheel, the rear wheel MIGHT be made to fit on the front. The rub was ever so slight but the shop didn't want me to drive off with it like that. So they put the front wheels (9.0"w x 20") back on the front. I did not test for any tire rubbing when turning to the extreme left/right since it was still on the rack. My new tires are 265x45 20R Pirelli AS Plus 2s.
When it comes time to rotate my tires, I'm probably going to take off the front wheel and see just how much metal there is on that suspension part area and whether there's enough metal on there to safely grind down the point of contact. I'd never compromise the part's integrity or our safety so why would I consider this? Only because the amount of scrape was SO small and minor that it might require just a bit of smoothing down that suspension piece or maybe even just rounding it out to a wheel shape (I forgot the name of that part, anyone recall?). If it seems to require more than what I'm comfortable grinding, I'll punt. I can always buy 2 new front wheels for the rear, but that's obviously a more costly/involved process. Just so that nobody freaks out about this idea, I'll only consider it if the part was not to get compromised from a slight <1mm grind. This is so that this MX can have its tires rotated in the future. Hmmm, maybe I should do this after it's decided whether Tesla is going to replace our MX/MS front suspension part here in the US.
Maybe during daylight tomorrow, I should take some new pictures of the front 9.0"w wheels from the same angle, to see how much diff there is. And while at it, I could look for the scrape marks on the rear wheel before they crud over the scrapes, just so that I can document this for my records if/when I investigate or try this mod.
Thought others might like to know the result of today's wheel swapping experiment.
BTW: Having 265s all the way around with these Pirellis = no issue/alarm from the autopilot, drives well on the freeway (only put 15 miles on them so far though), and the noise seems a bit quieter than the stock Continentals, but that's very subjective.

Yup, that's an option. Which would you recommend and price range? What are the pros n cons of using them?
