This study is looking at the health effects, not particle count per mile of car use. A similar study looking at tire dust would also be interesting.

Yes, the quantity and hazardous nature of different forms of pollution does need to be taken into account.

Unfortunately, tyre pollution seems to be more hazardous and produced in greater quantities:

None of your linked studies even come close to supporting this claim.

I don't doubt that tire particulates have negative health impacts on humans, but we don't really know which is worse yet.

The Guardian did a piece on this two years ago: https://www.theguardian.com/environment/2022/jun/03/car-tyre...

That is still talking about particulate counts, not health effects (the article does one study linking a particular constituent to salmon health effects.)
