Why do they ask what size wheels?

    When you change wheels on a model 3, this can pop up: 28F45E3A-7723-4967-B847-F769943FDC81.png
    Why do they need to know that? What does it change on the car?

    Wheel revolutions per unit of distance. So it effects mph calculation, for example.

    I guess that implies that they assume stock Tesla wheels and tires. In my case it is aftermarket in non standard sizes so maybe none of the answers are quite right

    That should not change considering the same outer size of the tires. 20” wheels use 235/35 and 19” wheels use 235/40

    They're assuming Tesla wheels, but it affects tire pressure and efficiency ratings.

    Possibly so they can show the correct wheels and tires on pictures of your car in the user interface?
