A new study led by an international team of scientists highlights tire particles (TPs) as the leading contributor to microplastics and calls for urgent, targeted research to address their unique environmental and health risks.

Accounting for nearly one-third of all microplastics,
Reducing the size and weight of a car goes a long way for environmental impact. People seem to think it's just less fuel being burned.
In reality, there is a reduction of almost every consumable. Smaller tyres. Less tyre wear. Less brake dust. Less oil used. Less chemicals when washing. Less wear on the road surface. Less manufacturing emissions. Less disposal when it's done.
The relationship isn't linear either. Doubling the weight of the car results in about 10x the surface wear.
Edit for the downvoters: I’m not against EVs as a replacement for ICE, but they’re not an endgame solution. We need to reduce the number of cars, period, whether they’re ICE or not.
Rubber tire dust is also toxic to ecosystems, sometimes more than the plastic dust version. As the articles suggest, additives are also a problem, but additives matter to the integrity and qualities of the tires. Best to get rid of cars entirely.
Cars won't be gotten rid of entirely. But we can reduce their usage. Rideshare systems (non-evil ones, not just Uber/Lyft; a membership system has been tried in Europe and works well) could help reduce the need for cars.
If only we had the technology to put cars on metal tracks, oh and we could add power lines so that electric cars wouldn't need batteries. Hmm, next we could link the cars together so that only the first car has to overcome wind resistance
If we're just looking at the grinding of the metal wheels against the rails, it's very little. Some metallic particles are produced in the normal wear but ferrous metals easily react and oxidize into more inert and normal forms for life.
