Edit to note that this is apparently 78% of microplastics *from specific sources, including textiles and personal care products*, which is only 11% of total microplastics.

So about 8% of total microplastics is directly from car tires.

RT @jme_pew Turns out “microplastics” isn’t descriptive enough. We should be panicking about *tire dust.*

“Seventy-eight percent of ocean microplastics are synthetic tire rubber, according to a report by the Pew Charitable Trust.”

Road Hazard: Evidence Mounts on Toxic Pollution from Tires

Researchers are only beginning to uncover the toxic cocktail of chemicals, microplastics, and heavy metals hidden in car and truck tires. But experts say these tire emissions are a significant source of air and water pollution and may be affecting humans as well as wildlife.

@jamesjm @capntransit they use tyres more quickly due to weight but emit far less brake dust as brakes only used in emergencies or for the final bit to stationary

@JohnLoader6 @capntransit

Interesting. How much does it net out to?
Is it even something we can net out (brake dust and tire dust)?

@jamesjm @capntransit no idea - but when you drive an oil burner think how many times you use the brakes to gently slow down. In an electric that would, if set correctly be done by recharging the battery. It all depends on your driving style.
