But this also means that almost all of the wear is from trucks.

This whole meme comes from junk science (https://www.emissionsanalytics.com/news/pollution-tyre-wear-...)

> we found that the car emitted 5.8 grams per kilometer of particles. Compared with regulated exhaust emission limits of 4.5 milligrams per kilometer, the completely unregulated tyre wear emission is higher by a factor of over 1,000.

They took plastic shedded by a gas car on non-EV tires, and compared it by weight to safety limits for gaseous emissions. This makes as much sense as saying that a lump of coal has 1,000 times more carbon than the safety limits for carbon monoxide.

That doesn't pass a sniff test; emitting 5 grams of tyre rubber per kilometer, a 12Kg tyre would be completely vanished in 3000km but really they can last 60,000km with only the tread worn down beyond safe levels and the bulk of the tyre still there.

Looks like mg was changed to a g, though I'd suggest even then the estimate is too high (but probably to the correct order of magnitude).

What meme? The article you linked talks about tire wear. Not road wear. I didn't even touch on tire wear. Road wear is well studied. https://en.wikipedia.org/wiki/Fourth_power_law

I really can't place your comment, you simply start talking about something completely unrelated to what I was talking about.
