The road wear is said to be proportional to the fourth power of axle load. http://www.cyclelicio.us/2014/fourth-power-rule-road-tax/ http://www.cyclelicio.us/20

That means you deal twice the damage by increasing weight by only 20%. Seems in line with electric car weight difference.
- dahfizz 4y agoYeah, that's my point. A single garbage truck is going to do more wear on the roads than thousands of passenger vehicles. Anything besides industrial vehicles is negligible.

- amelius 4y agoA garbage truck has many tires to distribute the load. Also they accelerate/decelerate differently.
- dsfyu404ed 4y agoThe rear tandems of a semi or heavier straight truck (garbage truck, dump truck, etc) occupy roughly the same road area as your car and may be carrying the weight of ~10x your car. The contact pressure is also much higher (100+psi tires vs your 20-40 or so).
- dahfizz 4y agoPer OP's report, what matters is axle load. A typical garbage truck has 2 or 3 axles. Let's assume 3 to be conservative. A fully loaded garbage truck weighs around 50,000 pounds. That's 16.6k pounds per axle, vs a Tesla Y's 2.2k pounds per axle. Doing the math, a single garbage truck does as much road wear as ~3,300 teslas.
