I don't think you can tax tires high enough that it will make a difference, but the same is also true if we attempt to tax by weight. Any tax is going to be the equivalent of slapping €10 on a plane ticket. It's not enough to stop the behaviour, but might be enough to keep some people driving on dangerously worn down tires.
It also doesn't matter if the car is an EV or ICE, the behaviour we want to limit is driving. The idea of taxing the tires could of cause lead to development of tires that doesn't shed microplastic.
