It's not though, rendering the point moot. They are two vastly different materials with different models of wear.
A quick thought experiment would make this very apparent: Do trucks need to replace tires at magnitudes less distance travelled than cars? Do cars tires last 100x longer than motorbike tires?
- throwaway894345 4y agoYour thought experiment incorrectly assumes trucks, cars, and motorbikes have the same number and size of tires. Trucks have more, larger tires to allow for more wear between replacements.
- Grimburger 4y agoIs it the magnitudes more though rather than 8x or 2x? I've seen it often said that a fully loaded truck is equivalent to 1,000 cars wrt road wear. Even accounting for tyre numbers and thickness/sizes, it doesn't add up. > Considering that the truck has eight axles and the sedan has two, the relative damage caused by the entire semitruck would be 625 x (8/2) -- 2,500 times that of the sedan. https://www.insidescience.org/news/how-much-damage-do-heavy-trucks-do-our-roads https://www.insidescience.org/news/how-much-damage-do-heavy-...
- throwaway894345 4y agoIt seems like you’re agreeing that it’s orders of magnitude, which supports my point. I’m not sure what point you’re trying to make. :)
