That picture appears to be a tire that wasn't quite wide enough stretched onto a wheel. Tires don't typically look like that unless someone did something at some point.
That is the size Tesla has on the Y... and they do indeed look like that. Your MYLR shouldn't be any different (from factory anyway).
The issue is that tires are measured in width at their "bulge" or rather, the widest point of the sidewall. The tread face is narrower than that.
255 sidewall is 10". TireRack doesn't give a all the normal specs for the DWS 06+ in 255/40/20 size, but it did have the tread width, 8.9".
And while the wheel is "only" 9.5", that's measured where the tire bead sits (on inside). The lip will extend out another 1/4" or so per side, so the wheel is basically 10" (or more) when measured on the outside.
So, when you put a tire, whose sidewall bulge is already close to the outer wheel width on, they look like that.
It won't matter what tire from what brand, so long as the sizes are close, it'll do that.
Sorry had to change format as the original was not acceptable.
That is the 19" Gemini wheels, so there's a wheel cover on it, making the "wheel sticking out" even worse.
The only way to avoid that look is to undersize the wheel width or oversize the tire width (compared to factory Tesla specs).
Most other car brands don't look like that because the tires are wider in proportion to the wheel (compared to Tesla, anyway).
Examples of my previous cars. 2010 Honda Fit Sport from factory had 185/55/16 tires on 16x6 wheels. So, even if you add about 1/2" to the wheel width (now 6.5"), that's still about 3/4" narrower than the 7.3" tires. My 2019 Honda HR-V had 215/55/17 on 17x6.5 wheels from factory. Again, +1/2" makes the wheel roughly 7" wide vs the almost 8.5" wide tires.
Oh, a few different sets of wheels later and my Fit now has 205/45/17 tires (DWS 06+) on 17x7 wheels... and they look just as "stretched" as my MYP tires look (255/35/21 on 21x9.5 and 275/35/21 on 21x10.5). In this case, the sidewall got shorter and that made the difference between tread width (again, narrower than the measured sidewall) and outer wheel width even more pronounced.
