Heavy EVs contribute to increase of particulate emissions

Putting bigger battery packs in EVs can boost range, but a new study suggests
it could also lead to a major increase in particulate emissions—from tires.

Bigger batteries in EVs could lead to colossal boost in particulate emissions—from tires, study suggests

Emissions Analytics performed chemical analysis of hundreds of new tires and now concludes tire-wear particulate emissions are 1,850 times greater than tailpipe particulate emissions.

Oft repeated, regularly debunked as much of tyre wear comes from a mismatch between wheel and road speed and the slippage results in wear. Highest with manual cars lacking electronic anti-slip controls, higher with ICE automatics, lower with single-speed EVs with anti-slip tech.

I also think one-pedal driving helps - as a situation develops, you lift off accelerator (little tyre wear) & then if braking needed it starts at a much lower speed and kinetic energy isn't linear, so much less tyre wear.

Stats on tyre wear compared to equivalents might be useful but couldn't find any.

Teslas are more efficient, better designed, do more with less kWh, which helps

According to quick google search weights of Teslas aren't more than ICE equivalents.
BMW 3 Series/Kerb weight 1,520 to 1,955 kg
Tesla Model 3/Kerb weight 1,726 to 1,847 kg
BMW X3/Kerb weight 1,810 to 2,095 kg
Model Y 2056 kg

With the rate of advancement of battery technologies, I seriously doubt in 10 years batteries will have the same weight densities as those of today. But the pursuit of longer and longer range may keep the weight up even if they become lighter per kWh.

Less than 10% of the particles are smaller than PM2.5. These larger particles are not nearly the same threat to human health.
Also, we're talking about tire rubber here, not CO2, CO, NOx, SOx, etc. which are real threats to health.
