    Generally the wear on tires is proportional to the wear on roads, since both are effectively grinding against each other with grit as the grinding medium in between. It would be harder to find a more accurate way to measure an individual vehicle’s contribution to road wear, given that weight is such a large factor.

    If you used mass surveillance to record exactly how many miles everyone drove and record exactly which vehicle model they were driving for each mile (to know the vehicle weight), you’d still miss out on the cargo factor. For transport trucks that’s the biggest factor, since an empty trailer weighs far less than a full one (and different types of goods have radically different densities).

    Of course we already know how much transport trucks weigh and how many miles they drive, since transport trucks are required to go through weigh stations and drivers have to keep detailed logs of how many miles they drive (and hours they drive consecutively). The issue then comes down to consumers and other business vehicles (pickup trucks etc).

      None of this is accurate:

      Generally the wear on tires is proportional to the wear on roads, since both are effectively grinding against each other with grit as the grinding medium in between. It would be harder to find a more accurate way to measure an individual vehicle’s contribution to road wear, given that weight is such a large factor.

      Surface wear on roads from tire contact is not a concern, the damage is done due to a combination of compression cycles (the 4th power law) and weather. The 4th power law being that road wear is equal to the 4th power of the axel load.

      Your tire wear rate is based on so many unique factors, with vehicle weight being a relatively minor one. Force of accel/decell/turning, suspension tuning, tread, rubber compound, road material, etc.

      Your tire rubber is not grinding away the road surface. It’s wild that I even have to say that.
