Not OP, but tire dust is a real problem. It’s one of those things we haven’t studied until very recently. It’s just gone under the radar because it’s easy to point at tailpipe emissions.

Now are EVs worse? If we compare the same class of vehicle, EVs are going to be about 20% heavier, so yes, they’re going to create more tire dust. Is that worse than the tailpipe emissions from a gas vehicle? Probably not. But it’s deceptive to not include tire dust when comparing emissions between the two vehicle types.
Any chance you can source your numbers? I tried to do the same calculation for my 18 year old gas car, and it came out a being a wash.
Finding hard numbers on the energy cost to build a new car was tough - the green sites showed the EV car poofed into the world with magic and butterflies, while the gas-centric sites made it sound like it took the entire world’s GDP to produce a single EV.
Also disheartening, the very few sites I could find that would list replacement costs for a battery pack had the price higher than the vehicle itself - IE, when the battery pack goes, you throw the car away & buy another one. That’s been a huge turnoff for me.
