Okay, the expensive tires thing is a problem. I did a little math.
Let’s say you get 50K miles out of a set of tires. At 25MPG, with an existing fuel tax of $0.50/gal, switching that to a tax on tires would amount to $250 per tire for a set of four to equal out. You’d ultimately be paying the same amount, but attaching it to the tire would make that all come up front. And then, yeah, you’d have people driving out of state for tires (if neighboring states didn’t do the same thing), as well as driving in to the state for the cheap gas.

Bah.
Note that most EVs get nowhere near that. The faster acceleration, higher torque, and heavier weight chew through tires.
So a flat tax on tires would results in EV owners paying more even though they don’t damage the road significantly more than petrol vehicles.
Doubt
Most road damage comes from large vehicles like trucks and busses.
