Tire wear is proportional to vehicle mileage and weight. A tire tax would effectively do the same thing while being easier to implement.
Incentivizes not replacing tires which is bad for safety and all.
Is it easier to implement? Maybe, but not really.
An alternative and would just be an annual inspection. Some states already require this, many just emissions. Just have it as a blanket annual safety inspection requirement for all vehicles, including emissions for the necessary vehicles.
I don’t know why you’re being down voted, but yes the mileage every year is recorded and taxed. In my state if you drive less than 10000 miles a year you get a discount on your inspection.
It’s because some people despise the idea of inspections.
Because ensuring the basic safety of a 2-3 ton hunk of metal flying down the road at speeds up to 80mph is apparently government overreach. Or because it’s an inconvenience to have to take it in once a year. Or whatever other bullshit reason they try to justify in their heads that basic safety inspections are a waste of time and resources. You know, shitty people.
