Every year, billions of vehicles worldwide shed an estimated 6 million tons of tire fragments. These tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our food. Researchers in South China recently found tire-derived chemicals in most human urine samples.
You can’t really engineer away the need for friction, and if there’s friction there is going to be wear.
If EV tires were much better than normal tires with the same grip levels and somehow magically less wear, all tires would adopt that technology.
Not that I’m a materials scientist, but EV tires don’t seem much different than other “economy” tires, other than a higher load rating.
There is actually a lot of small details that make EV tires different than regular tires. Nothing that helps with particle emissions, though:

All the EVs I see sold around where I live (Norway) come with the same eco tires as ICE cars. The heavier ones like a Tesla Model X just comes with the same tires rated for higher load. (And the extra foam inside for sound dampening, but that’s an option for most tires) The Model X also happens to be delivered with the same tire they put on the very much not EV Ford Explorer.
I know nothing about the tires on the Teslas or the non EV ford explorer, or even what tires are fitted in Norway. But the Hyundai Ioniq 5 I bought in Denmark last year came fitted with Michelin Primacy 4 tires, which are indeed EV tires.
What makes it EV and not just an eco tire? On Michelins website (Norwegian one) and various tire shop websites it just, an eco tire.
The staggered tread pattern, the stiffer rubber, the profile of the tire, and the sound dampening foam inside the tire. There’s nothing stopping you from mounting these on regular ICE cars though.
Here’s a video explaining more about EV tires:

Yeah my point is that this is… just an eco tire and not specific to EVs in anyway.
Did EVs cause eco tires to advance a lot? Yes.
Are they different from other eco tires? No.
Are they different to other tires in America? Yes because they didn’t really have eco tires before EVs.
