I recommend reading it. It's actually pretty well done.
Secondly, the report itself and common sense dictate that regenerative braking on EVs (or hybrids) greatly decrease brake usage, therefore brake dust. Some EVs have "one-pedal" modes where you don't use the brakes at all in normal usage.
Looks like tire issue is a toss up, and it depends on what the type of tire and how you drive. The much higher torque on an EV and a heavy foot will wear down the tires a lot more, but that has more to do with driver behavior than EVs.
Also, this whole issue is kind of a red herring because tractor trailers and heavy pickups and SUVs are a much, much larger source of brake and tire dust, and overall particulate pollution.
You are dismissing the weight factor a bit too quickly. Many EVs regardless of their size weight as much as some ICE heavy pickups, especially as the trend of driving SUVs hasn't disappeared with EVs.
EVs don’t actually use their brakes that much due to regenerative braking being the dominant mode. They are certainly heavier, though, which affects road and tire wear.
Road wear is not an issue for 99% of consumer vehicles. Roads are impacted by loaded semis, not a 3-6k lb vehicle. Same goes for brakes as most EVs implement regen braking.
