Well, no, we don't know that & that's prob false, it's just all plastics.
Tire microplastics just get circulated faster bcs they get grinned to a fine powder as part of their initial use (& that float gets flushed away with water). And the stat is stated for water or air.
Which is a problem, I'm just saying that we are producing a much larger scale of this problem that we can currently detect (and detecting microplastics is still in it's infancy even in lab conditions).
But sooner or later all petroleum based (non-biodegradable) plastics get to be microplastics, we just won't be around to see it.
Microplastics are the sedimentary boundary that will mark the current extinction event in rocks.
You can weigh new tires and compare them to weights of replaced tires. That would give you the low end estimate environmental tire microplastics deposited based on tire sales. I can't imagine its not a massive number.
