EVs have must less brake dust because they rarely use the brakes. But EVs don’t fully solve tire dust yet. HOWEVER, they make it a problem worth solving. When you’re comparing to diesel particulates (which are actually an enormous problem...) and fossil fuel smog to tire dust, solving tire dust doesn’t seem very pressing. But it would if we switched to EVs.

And there are possible solutions to tire dust. Changes to tire formulation, better road maintenance and mitigations, possibly relying more on tunnels (which we should do anyway in cities, even if it’s more expensive... and EVs make it much easier). Once fossil fuels are solved, it makes tire dust the next problem we can tackle.

So don’t use tire dust as an excuse to not transition to electric vehicles. Don’t let the perfect be the enemy of the much better. (And public transport can also generate particulates... tire dust, dust from rails, brake dust, and especially diesel particulates from buses.... we need to electrify everything.)

EDIT: And I don’t want to use this an excuse to NOT do public transport, only to argue it actually has much the same problem, but in case you don’t believe me on the rail dust thing: https://www.osha.gov/laws-regs/standardinterpretations/1996-... https://www.sciencedirect.com/science/article/pii/S004896971...
