But the tires are individually controlled - less slippage - and the brakes are regenerative. As a bonus, NYC is pretty much best-case scenario for the latter.

Not relevant for normal driving. The tires aren’t spinning appreciably due to acceleration except in brief moments with aggressive driving.

EVs can actually have higher acceleration related tire wear because they weigh more and have more instant torque on demand.

A lot of consumer EVs have filtered throttle pedal inputs to reduce the torque spikes though.

Not all tire wear is when skidding out. A car tire's contact patch is several inches wide (especially on trucks/SUVs where extra-wide tires are often used to give a more premium look), so any time that wheel is turning a corner, there's a portion of it at the outside and inside that's rotating at a different speed than the pavement beneath it is moving.

There's also the regular deformation of wheel just in the course of regular rotation, which is where the majority of highway wear dust comes from.

With extea weight and tire size, evs will have more slippage. It isnt about the entire tire slipping against the ground. It is about tread patterns slipping as the tire rolls at any speed, especially in corners where car tires cannot ever avoid slipping.

While this is generally true, tire wear is known to be generally faster on EVs due to their weight and instantaneous torque when accelerating.

Which, as an EV owner, feels like an "oh no, my steak is too buttery" kind of problem to have.

The instant torque also comes with better control over it, though. I don't doubt it's a thing, but I do doubt it outweighs all the other environmental benefits.

It’s the forces that accelerate the wear. Significant wheel speed is a rare occurrence in normal driving, but acceleration, cornering, and braking forces are ever present.
