> Indeed, the scale of these emissions is significant. Particulate emissions from tires and brakes, particularly in the PM2.5 and PM10 size ranges, are believed to exceed the mass of tailpipe emissions from modern vehicle fleets, as per a study published in Science of the Total Environment this year.

This simply cannot be true. Tailpipe emissions have more mass than the gasoline that gets burned. A car uses several liters od gasoline per 100km. I am pretty sure no car loses several kilograms of tire or brake matter over 100km.
