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.

The major EVs by volume are Teslas, which are definitely tuned towards much sportier than a “regular” ICE vehicle.
