Did you consider the weight for the full vehicle, or per-axle? The per-axle figure is the relevant one and would probably flatten that figure out quite a bit.
They are also much more stringently enforced on commercial transportation vehicles, which require annual inspections and serious preventative maintenance to pass which does already add to the cost of operating these vehicles.
Their per-mile consumption is higher as well, which aside from being bad for the environment, already means they are consuming much more fuel and paying a higher tax as it is.

Transportation, on the whole, accounts for 28% of greenhouse gasses... but it also enables the society that we live in and our own personal mobility within it. Electricity is nearly the same at 27%. You can shift the source, but you cant eliminate greenhouse gas from our way of life.
Also basically every every other material good.
I think people would probably scream pretty loud if food suddenly jumped in price 10x, but maybe we could handle it like most places handle sales tax? Exempt trucks carrying food/necessities and tax everything else.
The cost of transportation should just be included in the good. That way, if someone comes up with an ingenious new method of urban farming or something, they'll get rewarded in the market for cost savings.

If you want to EV tax me for road wear fine. Please tax trucks at least 1000x, and please tax all gas burning cars for the lung cancer and other negative externalities they cause.
