Brake yes, I don't see how it would help tire wear (assuming you slow down at the same speed). Electric cars typically have higher tire wear because of the increased weight + typically higher torque/acceleration.

This is due to good traction control. The driver assist systems reduce slipping by utilizing the electric motor's rapid power adjustment. This system is much quicker than in ICE vehicles, where it is based on braking and limiting engine RPM, Liukkula says. I dunno if anyone's done a good scientific study on this.

  In addition to this, people are aware of the existence of regenerative braking, and that it works better when decelerating less aggressively, so they do. Which puts less wear on the tires.

  Sounds like shit to me. How much time do you spend spinning your tyres and braking so hard you skid?

    You don't have to fully skid the thing to see a benefit from better control over the breaking process. From the skid marks I've seen on the highway, rare skids seem to pull off a significant amount of rubber in one incident.

    The tires cannot generate any longitudinal acceleration with zero slippage. This slippage is what causes wear. (As a driver, though you perceive there to be zero slippage without wheelspin or sliding the tires, there is slippage between the road and tire anytime the tire is exerting a longitudinal force on roadway.)

  This was, in my experience, not true. Ask most Tesla owners as well. The heavier car + much better acceleration created more tire wear than any improvements to traction control from faster power response (though I'm not sure intrinsically why that would reduce wear - ICE cars can apply brakes to a slipping tire just as well as an EV, and instant torque doesn't feel like it would do anything positive for tire wear). Fitting lower rolling resistance tires on ICE cars would provide any of the same benefits that EVs receive.

    Tesla != EV. My Ford Focus EV, while having annoyingly skinny tires have lasted 60k mi and 5+ years. It's no slouch and I'm a lead-foot. That Tesla is pushing run-flats may be why they wear out so ridiculously fast.

    Part of the issue is that modern run-flat tires have stupidly low lifespans, like 20K miles. I have a Tesla and opted for non-run-flats with my latest change and I don't think my tires wear any faster than other cars I've had.

    The tires my Tesla came with lasted only about 20,000 miles. I replaced them with better tires and those are not even close to wearing out after 30,000 additional miles.

      Which tires did you switch to?

  Spinning the tires will obviously accelerate wear, but I don't think that's the source of most of the tire wear we see in the wild. Spinning the tires isn't all that common, but tires still wear down.

  Sure, it helps. However not only are EVs heavier, but there's a significant incentive to use narrow tires (for the weight) to increase efficiency and range. As a result, while not skidding, it's easy to accelerate, brake, or decelerate enough to scrub the tires hard enough to wear quickly. It's pretty well known that Teslas are hard on tires. One benefit is I rarely use brakes instead of regenerative braking. Having AWD does seem to help on that front.

Anecdotal evidence: I regularly manage to (unintentionally) spin the wheels in a petrol car, but I have never managed to do it in an electric car yet, despite trying out the full acceleration. So while the torque is undeniably greater, apparently the motor management control is also better, so it can deliver maximum acceleration without increased tire wear - at least in the electric cars I have been driving (mostly BMW i3).
