A typical ICE car will consume at least 500 gallons of petrol (gasoline) per 1 gallon of tire tread worn. The environmental impact per volume of tire is certainly greater, but it's not remotely five hundred times greater.

I'm not saying we should disregard the issue of tire pollution. But if it was as serious as you suggest, it would be making more headlines than it is.

Why wouldn’t it be 500 times greater? Gasoline is combusted for energy, converting most of it into mostly harmless byproducts; tire tread is just released as is.

		The best evidence that tyre tread is significantly less consequential than gasoline consumption is that such criticisms overwhelmingly arise in discussions of electric cars.
