Every year, billions of vehicles worldwide shed an estimated 6 million tons of tire fragments. These tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our food. Researchers in South China recently found tire-derived chemicals in most human urine samples.
There is in fact such a thing as an “electric car tire”.
Fundamentally you are correct that they are in essence just tires rated for the weight class, but there’s more to it than just that.
Electric car tires are usually made with a stiffer rubber than comparable combustion cars, this is mostly to handle the additional weight, but they also stagger the tread pattern, and some have foam inside them, both to improve the noise and acoustics of them. Something that wasn’t a problem when there were a noisy combustion engine running. But in an electric car you don’t have the engine noise, and therefore hear a lot more of the wheel noise.
None of this help with the particle emissions, but there is in fact such a thing as an electric car tire.

This is what I’d read, this guy specifically states that the tires are much stiffer to counteract the increased wear of a regular tire from the 20-30% increase in car weight. Anyone know of any good studies on this?
