Is that true? EV have much higher emissions of micro plastics and pfas (or variations thereof) due to increased tier degradation. EVs are typically way heavier than similar ICE due to the batteries and combined with the higher torques, tires wear faster.

I find those claims highly suspect: I own an EV and haven't had to change the tires more often than I did on a gasoline-powered car. My EV bought in 2021 still runs on original tires and they're fine (although I do change from winter to summer tires, so that's 2 sets technically).
I suspect black PR, and there is always a grain of truth in black PR: emissions are indeed likely to be higher. Probably not "much higher" and probably not in a way that really matters.

This isn't "black PR". It's comparing apples and oranges. But throw non-EV tires on one and you'll definitely chew those tires up much more quickly [0][1][2][3].

1) this is not the only or even the overriding factor when comparing the two. There are engine emissions (none for EVs) and braking (EVs have regen braking)
2) There is a trend for larger, heavier ICE vehicles in the USA as well. Big trucks and SUVs. It is very selective to argue against EVs in this way without also arguing against these.

One thing that differs is brake wear. My car is ten years old and still on its original brake pads and discs. The regen braking is amazing for avoiding mechanical braking. So that means less particle emission from brakes, compared to ICE.

Well no, it's not "the same". We have things like physics to tell us that more torque and more weight means more tire wear, despite your anecdote. There are even studies on this. They also have a greater impact on road wear.
EVs have many advantages over ICEs. I don't understand why people have to lie and say they are worse nowhere.

No I'm sure fracking and pipelines and all the crap the oil industry needs just to exist does not have any pfas or micro plastics

Additionally, due to the fourth power law [0], you only need 20% weight increase to obtain a 2x road wear. Asphalt/concrete production is also accompanied with substantial emission, although progress is made to reduce it [1].
Is there a break-even for weight vs emission reduction? And if so, is it somewhere between personal and cargo vehicles or is it 'EV always better'?
Are we trading 'well-known and bad for global environment'-emission for 'poorly-understood and possibly very bad for local environment on a global scale'-emission?
Of course, with the available information EVs seem to be the better solution, but it should not prevent us from researching/solving unknown effects or being careful choosing a single solution on such a large scale.
