> "Weight" is not the correct factor to optimize, basically.

Is it not? Particular matter from tires is a major factor in air pollution and the heavier the vehicle the more that ramps up.

Absent numbers, I'm gonna go with "Mass-dependent increase in tire-derived particular air pollution" isn't the right factor to optimize either.

Its not just tire pollution but road wear

Alright? It's not clear by implication what you actually do want to optimize for but the weight/particulate problem is a fairly well-known problem. For instance, from the California Air Resources Board: https://ww2.arb.ca.gov/resources/documents/brake-tire-wear-e...

It's something the tire industry has been fretting over for a while: https://www.tiretechnologyinternational.com/news/regulations...
