Also, is the proportion you're using for scaling per axle or per wheel? Since the likely cause of wear on the road is ground pressure the latter seems more likely to me. In that case your typical 18 wheel semi is a 9 axle equivalent; and using the weight numbers you plugged in gives (4400/2000)^5 = a 24 to 1 ratio. Google's indicating 6-8 mpg for a fuel efficient semi which puts them at a ~3-5x discount vs typical passenger cars.
