But in the comparison of tailpipe emissions (0.02 mg/km) vs tire emissions (36mg/km), I know which one I’m more worried about.

Nick Molden of Emissions Analytics seems to think that the heavier the vehicle, the worse the wear on tires seems to be (though it greatly depends on driving style and torque). That’d probably mean heavy EVs and SUVs are the worst for this.

Not that bicycles are completely clean- but there’s probably a time in the future to worry about bicycle microplastics- after the cars have been phased out.

We’re talking about personal subjective measures, so there isn’t an objective “right” or “wrong” answer, but there’s a bit of a double standard to your logic. Here’s what I’m seeing from your stance:

ICE vs EV = even though EVs better, its still a car so still not good enough so use third choice "bicycling"

EV tire pollution vs bicycle tire pollution = bicycles produce the same type of pollution but less of it, so its good enough

It seems like your logic should follow:

EV tire pollution vs bicycle tire pollution = bicycles produce the same type of pollution but less of it, but still not good enough so use third choice “walking”

You could argue “walking is too slow, while biking is faster and at least less destructive than worse alternatives for fast travel”. However, that would also seem to introduce “bicycling is too slow, while EV is faster and at least less destructive than worse ICE alternatives for fast travel”.

So you like bicycling, and there’s nothing wrong with that as it is purely subjective and there isn’t a wrong answer, but if you’re adhering to your logic, you should eschew bicycling for walking as its less destructive using an objective argument.

  I’m not sure if a study exists for it, but I’d assume walking produces more microplastics/km than bicycling because of how soft shoe rubber is and how scrubby the action is. Who knows. There is a study I saw that said that walking produces more CO2 per km than cycling, but I’m not sure if this is parallel to microplastic emissions.
  
  The logic will make sense if you think that tailpipe emissions are so litte, it’s almost not worth considering in comparison to tire emissions. So the next step is to say “so how do we limit the microplastics in the air and in the ground on a necessary part of transportation”- the answer is to make it smaller and lighter. And if you want to go distances that you can’t get to by bike, that’s where public transportation comes in.
