> Electric cars tend to use low rolling resistance tires (potentially less wear… if you’re experiencing less rolling resistance, that means less energy ends up being used to produce wear, so less wear occurs… in part due to geometric effects and partly due to composition of the tires). Electric cars are also fairly comparable in curb weight due to massive weight reductions elsewhere, plus improved traction control (and the more gentle regenerative braking) means less wheel slippage and wear.

Do we need to go this deep into our analysis? I would think ((pi*radius^2)-(pi*(radius-tread_depth)^2))*width/miles would tell us pretty much everything we need to know about tire emissions, and most EV owners in my experience will acknowledge spending much more on tires for the same # of miles or spending the same for a good bit less # of miles. I'm not sure what the dimensional differences are on your average EV tire purchase versus your average ICE tire purchase, but if we look at model 3 base tires vs civic touring tires (biggest stock civic tire sold):

M3: 235/45R18 10/32 (Primacy MXM4)

Civic: 235/40R18 9/32 (Eagle Sport A/S)

so at least as far as stock tires M3 should have more total tread than a similarly sized/similar TCO vehicle given the larger aspect ratio and deeper tread depth. Unfortunately I can't find any non-anecdotal data on how many miles they would each get.

Of course I agree with pretty much everything you said but I do think tires are an important conversation to have around EVs, particularly when prices come down and budget conscious buyers start putting cheap, loud, fast wearing tires on their EVs.
