Using cars less (investing in public transport) and reducing the average weight of cars sensibly would make already an extremely huge difference.

The difference in tire wear between a Corolla and a EV SUV is quite huge, e.g., you're gonna change tires way more often on the second one.

This feels like a distraction, though.

If car tyres cause unrecoverable pollution then we don't need to reduce that by half or something, we need to almost eliminate it.

That means that we need a type of car tyre which does not cause this pollution.

I don't see how would that be possible, tires work based on traction which depends on friction, you're gonna have to lose material.

At the end of the day, I disagree with you, you play with the cards you have at hand, and at the moment tire technology isn't gonna change, so at least we should push for using less and smaller cars.
