isn't that at least partially caused by the rubber tire particles?

Could be! I don't know enough to say what the ratio of exhaust to tire particulate is on the average road.

In either case it's a good physical representation of how much particulate we are exposed to every day. Maybe having it trapped in dirty snowbanks is better than having it getting kicked up into the air during a dryer season.

Road particles, brakes and tires dominate that massively.

		Maybe 'Dwarfed'? Dominated to the point of insignificance? Anyway, did you understand it?

If it's particulates from tires then heavier EVs are probably making that worse not better (partially offset by regenerative braking, but only partially).

		EVs produce more tire dust, but much less brake dust and exhaust (even when powered by coal plants). The net effect is a massive reduction in dust and particulates. Some modern tire additives are incredibly toxic to fish. They’ve been banned in the EU, but for the very special corner case of driving in sensitive watersheds in the US, it’s possible EVs are worse on that one dimension. Of course, we could just ban the recently approved additive, and completely solve that corner case problem.
