Should changing from 21" to 19" wheels change the displayed range?

If you have this done at a SC, they will normally make the change for you.
Seems like with the latest Model 3 software update, you can specify the wheels yourself and it adjusts the range calculations accordingly in addition to the avatar image.
Would love to be able to select the wheel size in my Model S like how it is now possible to do so with the Model 3.
You can ask them next time you are at the service center.
When I got my wheels, I bought them from the SC so they swapped the wheels and made the correct changes in the software. I had a bad experience once with a previous car and wheels and tires are something that I always let the dealer (in this case Tesla) take care of.
The video posted earlier now shows that Model 3 owners can make the wheel change in the software on their own and it affects the displayed range as well. Hopefully the same feature will be available for Model S and X so we can also set the correct wheel size and get the correct range based on the wheel size.
I've put plenty of miles on both my 19" and 21" wheels. When switching tire size, rated range is not changed. Also, at least for me, the larger 21" wheels had exactly the same wh / mile efficiency the 19" wheels did. That said, my 21" setup is square so don't have the wider rear staggered setup.
Based on the recent software update for the Model 3, Tesla agrees with the basic premise that all else being equal, the smaller wheels result in greater range. This is one of the many reasons the first change I made to my car was replacing the 21" wheels with 19" wheels. In the Model 3, as you assign different wheel sizes, it accordingly adjusts the projected range. This is precisely what the OP was looking for on the initial post of this thread.
Here's the video from the previous page showing the new wheel size setting in the Model 3. Would love to see this same setting for the Model S.
Anyone received 2019.32.1?

I just got it, nice to have the image user-updatable, haven’t had the chance to drive and see the updated numbers.
Edit: Niiiice it updates in the app too. Slick. A little feature that’s nice to have.

That's great to her the wheel interface is also available for the Model S. I never saw a difference in range after I switched from 21" to 19" wheels so it would be interesting to see what happens when I confirm and make the wheel size change.
I'm still on an older software version so I hope I get the 2019.32.1 update soon.

I switched from stock 19 in 245s to staggered 21 in Vorsteiners wrapped with 265/285 Michelin’s and my measured wh/mi changed from 365 to 385, so about 5 percent less efficient
I have FSD, HW3 and reckless downloading of alpha software selected.Strange that everyone is getting 32 and I'm stuck at 28
I also have Advanced Mode selected for downloads. I used to get updates very quickly and I also have FSD but HW 2.5.
IDK, maybe they try to initally release the same number on both H2.5 and H3. Since there are fewer HW3s out there, they get updated more quickly on a percentage basis.
That actually makes sense.
Thanks for testing the software for us!
Have they fixed the USB music player so that it resumes music when you get back in the car?
I don't use usb, but I just tried it. I let the car lock and then re-entered. It started playing were it left off. Do you have to wait for the car to go to sleep?
