    I think the 20's would be a nice compromise.

    I asked my local service center about this for winter tires given that I wasn't happy with the stock S options. I was told (for what that is worth) that they couldn't do it, because although the tires would fit on the car, the fronts might scrape when the steering wheel is cranked all the way to one side.

    I can't imagine that it wouldn't fit. The platform is the same...

    The 20" wheels should fit perfectly fine but the tires on the X I believe are bigger so you would have to get appropriate size tires to keep them in line with the Model S wheel Base.

    I thought of this as well as 20" tire options are cheaper than 21".

    However, I haven't ever seen any evidence that they are the same offset. What the service center said seems to imply the x wheels may have a different offset causing rubbing at lock...

    I'm sure someone will try soon enough!

    Looks good! Do you have air suspension or coils? It looks like it has been lowered. Any rubbing over bumps or turning?

    With the right tires the 22" wheel will fit just fine.

    They're the same offset.

    Model S: 21x8.5" Front / 21x9.0 Rear w/ a +40 offset (in staggered, box uses a 8.5 all around) with a tire size of 245/35/21 Front and 265/35/21 Rear
    Model X: 20x9.0 Front / 20x9.5/10.0 Rear w/ +35 offset

    TST sells a 21x9.0 x 21 x 9.5 rear w/ +35 offset, so as long as the rolling diameter (adjusted by tires) is the same, there should be no issues.

    ---------------------------------------------------------------------------------------------------------------------------------------
    If you want the long version, keep reading. I used a wheel calculator to double check this.
    This one takes a lot of parameters. Since I didn't have all the data, I used two scenarios.

    1) I just made an assumption there was no room for adjustment. Meaning, I found the point of rubbing, and used the next value up. Based on that assumption, it would rub on the fender using a 245/40/20 tire on a Model X 20x9 +35mm offset wheel. However, this assumes there's only 5mm of clearance between the existing wheel setup and the fender (there's more than that on my car)

    2) So I changed my parameters. Assume TST did their research and their 21" wheels fit. I did the same assumptions to adjust so that TST wheels had no room for error. It found that a 245/40/20 tire on a 20x9 with a +35mm offset would fit the same as the TST wheels with less than 1mm difference in the overall diameter.
