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.

This company is working on a pollution capture device:

Very cool.

May I introduce you to the steel wheel rolling on a steel rail?

Not frictionless, so it will also slowly degrade over time. It just has so much mass built-in that it’s not obvious.

But, critically to the conversation we're having, does not produce harmful particulates when it does so.

Yup, make a rail to everybodys home instead, that will solve it.

It's worked before

This is measurable and actionable. Some tires pollute more, some less

The real changes are to make them less toxic! There are a bunch of approaches to take there.
