/comparable/ EVs are a massive improvement.

if more than half PMs come from tires and dust, I'm not sure

The emissions graph only considers particulates, so it's massively undercounting air pollution improvements from EVs.

Do you have figures for this? it says: "non-exhaust par­ti­cles represent 59% of PM10 and 45% of PM2.5 emis­sions", so about half of fine particles are non-exhaust (brake, tires, road dust). If you also count the fabrication process, the batteries, the new infrastructures and electricity footprint, the additional weight (for the same size), it's possibly a small gain over thermic engines, but nothing super obvious
