I have nothing to back this up other than I'd like to see a comparison between EV's and other luxo models for tire wear. Because the tire design matters a lot when it comes to wear. I'm a bit suspicious about the weight being the primary driver since I have a van that weighs 6000lbs and it doesn't burn through tires.

I can see two things. One maybe EV tires are spec'd to be more sporty. Or possible tires aren't optimized for the extra weight.

Pointed comment: No one but no one cares about higher weight trucks and suv's at all when it comes to tire wear. Only EV's get singled out.
