Electric cars are not THE solution.
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.
