This was a revelation.
...Even so, 85 to 90 percent of toxic vehicle emissions in traffic come from tire wear and other non-tailpipe sources,...
So electric cars will mitigate only 10-15% of the environmental problems of the ICE cars?

If you follow the link to the actual research paper you find that it's 90% of PM10 and 85% of PM2.5
That is, not "emissions" in general but particle matter specifically.
This makes sense because modern cars have efficient engines and particle filters so that few particles are emitted from the combustion engine itself. The remaining sources are the tyres and the brakes.
But doesn't the point still stays that contrary to the popular belief electric cars would not bring about much change?
Research paper: ..it could be concluded that the increased popularity of electric vehicles will likely not have a great effect on PM levels.
As said, and as your quote highlights, this focusses on particles. But the main emission of internal combustion engines is CO2, and other nasty stuff like CO, NOx, hydrocarbons, etc. These are eliminated by electric vehicles.
Claiming that electric vehicles only move emissions to the electric plant is unfair at best.
Are there any emissions associated with that additional 125kWh of consumed electricity? If so, where? If not, why not?
PM2.5 emissions were only 1-3% lower for EVs compared to modern ICEVs. Therefore, it could be concluded that the increased popularity of electric vehicles will likely not have a great effect on PM levels. Non-exhaust emissions already account for over 90% of PM10 and 85% of PM2.5 emissions from traffic. These proportions will continue to increase as exhaust standards improve and average vehicle weight increases. Future policy should consequently focus on setting standards for non-exhaust emissions and encouraging weight reduction of all vehicles to significantly reduce PM emissions from traffic.

It's said that cars "produce" PMs this way even though they don't per se.
What I'm getting at is that if we reduced the amount of particulates added to the system, then surely there would be less to resuspend?
Unless there's some other, non-car related source of these. If so, why not address it instead?
