First, NY Post is kind of a tabloid. You gotta dig deeper. Here's the actual study: https://uk-air.defra.gov.uk/assets/documents/reports/cat09/1...
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.
Thirdly, tires is a different calculation. This looks like a fairly unbiased source (https://www.emissionsanalytics.com/news/2020/1/28/tyres-not-..., https://www.nokiantyres.com/company/news-article/there-is-a-...).
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.
