Model X tire sizes

[Mircea]

I would like to change mee tyres/rims. I have a lowly entry-level X.
My car came with 255 front 275 rears.
I know P100Ds come in 265 front and 285 rears.
Therefore there would be enough clearance for 265s in the front, and presumably it is possible to have them all around.
So, my questions are:
- is it ok to have it 265s all around? I am thinking of 26/40R21 or 265/45R20.
- is it ok to have 255s all around?
- would it be ok to have 245s all around?
The ok questions refer to regulations. Opinions relating to driving dynamics are welcomed.
I understand that on same aspect ratio the tire circumference is smaller, that is fine.

also a good question (and prolly my preference):
would 275s fir in the front? has anyone tried or should I give it a shot?

I see no reason why you have to "have" staggered wheels... only issue i see is going to big on the front will affect steering. you may get wheel rub when turning the wheel full left or right. A good performance tire shop should be able to check fitment of the various sizes.

@Mircea , be careful with this. Wheel/tyre size are not the only critical parameters. In the staggered setup, the offset of the front wheels is 35 mm, but 40 mm in the rear. If you install 40 mm offset wheels in the front, they will rub the suspension.
Note that the Tesla 19" symmetric winter package uses 35 mm on all 4 wheels.

Thanks for that @Solarman004.
