Considering a mazda with tyre size of 215/45 R18 with 1/4inch useable tread depth, that lasts 30K miles:
The mm^3 of rubber lost over lifetime (circumference * how wide the tire is * tyre tread depth) is approximately 2375922.431
Considering density of rubber at 650kg/m3, the weight lost over 30,000 miles is 1.54kg, which equates to 31mg/km and nowhere near 5g/km as claimed in the article. What am I missing?
