(which electric cars and trucks also reduce, because of regenerative braking)

Doesn't regenerative braking reduce brake dust, not tire dust?
Correct. And tire dust increases because electric vehicles are usually heavier
For semis this is irrelevant, as the GVWR is pretty much the same so EV mostly means you get limited on payload weight: in the US the feds increase GVWR limit by 2000 lbs (from 80k to 82k) for EV semis, but not every state has legalised that, and it's barely noticeable (EU has a much more aggressive bye, from 40 to 44 tonnes).
I doubt that's the case in America where gas-powered cars (/ trucks) are also huge and heavy.

A Model 3 weighs less than a Ford 150.

And a mini cooper weighs less than a semi. The thread you are in is about Semis.
My father who owns an electric car (I don't) told me that the increased torque eats away the tires much faster. Not sure how connected to the reality that is.
Correct, but I would say that is user error. You don't HAVE to accelerate faster.
Increased forces from similar speeds but with more weight in cornering wears down tires more in electric cars. Less so the torque myths
