Sorry, I probably phrased it in a confusing way, I was comparing the ratio between tire/brake and ICE PM 2.5 emissions for normal cars not saying that EVs are that much worse (the part about weight is just speculation).
As for the tire emissions, you are likely quoting the worst case scenario that was devised by emissionsanalytics. The reality is, that was a worst case scenario, if you actually saw tire wear that was significantly more polluting than traditional cars you would have tires that go bald in a very short period of time.
For example, the Micheline Pilot Sport all seasons that come on the Tesla Model 3 are rated for 45k miles, but typically get around 35-40k miles depending on driving habits. That is only 13-26% more tread loss depending on driving style. So how is it possible the tires are losing significantly more tread (and as a consequence, polluting more) but also lasting a long time?
