The article contains a caveat that tailpipe emissions only recently were reduced below tire emissions, and even then only in some places. Also, EV’s produce much less brake dust, and the article doesn’t compare that decrease to the 20% increase in tire dust. Anyway, this mathematical bound holds in the absolute worst case for EV’s. If tailpipe emissions used to be 51% of the problem and brakes were zero, then switching entirely to EVs would leave us with 60% as much particulate emission as we had before. It’s likely much lower than 60% of course.
