Pretty sure most wear comes from the back tires (I should say the "power tires" to consider FWD vehicles). Many electric vehicles accelerate quite quickly, which just wears their tires even more.

Braking is braking. If you're stopping in N meters, regardless of how the braking force is applied (regenerative brake vs discs), the tire is the artifact taking the load.

Even then, most cars don't routinely brake as hard as they accelerate.

Motorcycles, with their high performance, are notorious for eating rear tires much faster than front tires, and they can't be rotated.

Then, there's my vehicle, full time 4WD (not AWD, there's a difference), it wears its tires quite evenly in contrast to 2WD/AWD vehicles.

Braking is usually much quicker than accelerating, for almost all vehicles (because brakes can absorb much more energy than engines can output). For this reason, I suspect most particulates are caused by breaking.

I believe you mean most drivers. All of this talk about EV tires wearing faster than ICE tires is driven by people accelerating aggressively simply because they now can.

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.

It’s about the weight of the vehicle; aggressive driving just makes it even worse.

EVs are generally quite heavier compared to similar class of ICE vehicles.

		I don’t think so. Weight is a rule of thumb for damage to the road. Aggressive acceleration is much more of an impact to wear. All the people I know with EVs love the feeling of gunning it from a red light on when getting onto freeways. Yeah they don’t peel out, but that’s only because the control system stops them.

Electric cars are mostly drive-by-wire, so if the same driver input results in accelerating faster in an EV then I'd say that's the car's responsibility.

That makes no sense. Every car on the road, regardless of power source, has what amounts to an infinitely adjustable pedal controlling acceleration. The relationship between pedal input and actual acceleration varies between cars, and can vary even on the same car in different drive modes. How fast you accelerate is 100% under your own control.

If you put effort into controlling it, sure. Most people have other priorities, they push the pedal when they want to go and they leave it to the car to accelerate at a reasonable speed when they do. Mass-market cars should be built for the population that exists, and that means having a default accelerator-response that does sensible things for the way that normal people normally use the accelerator.

		> Most people ... push the pedal when they want to go and they leave it to the car to accelerate at a reasonable speed when they do. I'm going to need a source for that. There are literally tens of thousands of accelerator pedal types, with different hinges, different travel, different stiffness and different engines with different ECUs and different drive modes attached to them. There's no one default way to step on the gas that people would just pull out of muscle memory.
