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.
Yes, imagine if there was a fast and safe way of transport. Something like made to run on steel bars in order to reduce friction. I don’t know. I’m just imagining, I watch too much science fiction.
The wear rate should be proportional to the weight of the system (car plus cargo and passsengers, bike plus cargo and riders), maybe with some correction factors for things that affect wear rate like knobbiness.
Since bikes weigh a couple orders of magnitude less on average, the amount of tire wear material should also be a couple orders of magnitude less.
Edit: other lemmyer said wear is proportional to weight to the 4th power and that may be correct. I vaguely recall that from school now that they mentioned it.
If only there was a highly efficient mode of transporting people that didn’t use tires. Ah well, nothing can be done I guess.
My city’s metro system uses rubber tyres, :(

To be fair, the most efficient mode of transportation is cycling by far. I wonder if bike tires also contribute to this.
They do
I’m sure they do but it will be way less.

Assuming the material properties and physical design of the two tire types is identical, maybe
Bikes cause thousands of times less damage to streets so I wouldn’t be surprised if they also wear less.
And the size of bike tires is way less than a car tire.
Good point! Also much less weight.
