Damage to the roads increases with the fourth power of axle weight. It follows that all passenger cars heavy or not, EV or ICE are insignificant for road-damage.

One could surmise that there is a similar relation with tire wear and therefore pollution from them as well.

But taxing tires is I think a good idea as it is a consumable and the wear and it's impact can be directly measured.

The problem I see with taxing tires is twofold:

- how is taxing going to solve this problem, it's unlikely that it is going to have a significant impact on driving

- can taxes be fed into tire research in a way that reduces the impact on the environment? Are there any solutions that need funding?
