I did the calculation in Freedom Units and converted to grams per km. Assuming tires last 60,000 miles or 100,000km and got 0.1 gm/km. So matches your analysis closely.

Notable I put 60,000 miles on my cars tires since I bought it. They are due for replacement kind of whenever.

I hadn’t heard the term Freedom Units before, seemed obvious what you meant, looked it up anyway.

Universal measurements of American awesomeness. It encompasses all types of units (temperature, length, area, volume, speed, weight, GDP, etc).
