TFL upgraded to bigger tires on their Hummer EV and as you can guess, range was lost in this test. Cold temperatures also play into the range decrease but still a good look at how upgrading tires limits you.

If you went with bigger tires, please share your range stats below.

I think it depends on wheel design too. Generally, the more closed off the wheel the better the range. Rivian has 20 inch wheels that offer less range than the 21 inch wheels. I believe the Hummer was not designed with the intention to optimize range by improving aerodynamics but rather focus on overall design and sticking to a modern variant of the original models.
