Show this to be true.Yes, but, by far, most of the fuel is used overcoming friction.
Compare the enegry used to overcome friction over a 20-mile struch of road comapred to the energy used to climb a 3% grade for that same 20 miles.
Also, compare the energy used to overcome friction over 1/2 mile to the energy used to accelerate from a stop to 60MPH over that same 1/2 mile.
In both cases, assume a 80,000 gross and 18 standard tires.
Yes... altnough this adds to the price of a new truck.You don't need to replace the wheels; you manufacture the truck in the first place with those wheels
It also doesnt account for all of the existing trucks.
As you are happy to confim - if there were an overall a cost benefit to these, they's be more widespread.One new wheel and tire will cost less than two old ones as soon as the volume is pushed up by artificial means.
Your idea forces compamies to spend money thay they won't bet back for the tunnel-vision goal of reducing fuel use.
