I’d be much more interested in particulate pollution limits for tires.

How much of this is a solvable problem, insofar to the best of my knowledge there is no fundamental workaround for the fact placing heavy objects moving fast on rough surfaces generates friction which leads to the erosion of surfaces?

I think particulate pollution would be an acceptable outcome if the tires themselves were biodegradable over 10+ years. But to my understanding the vulcanisation process that's employed makes it impossible.
