Gasoline cars 2020: Exhaust 0.005 g/mile. Brakes 0.003 g/mile, tires 0.001 g/mile.
So exhaust + brakes produce 8 times as much PM2.5 as tires. So the argument but 'but but EV's are heavier and produce more PM2.5 than gasoline cars' doesn't cut it.
Also I've seen references that show natural gas heating isn't nearly as clean as portrayed.
Particulate matter from tires is more concerning if you live next to a major highway. However in cities it’s almost all combustion byproducts with significantly lower tire ware due to low speeds + lots of idling at stoplights. Which is why catalytic converters made such a huge impact.
Also, while most cars have some air filtration for the cabin the quality of that filtration can vary quite a bit. It can be well worth an aftermarket upgrade.
