Minor nitpick, but tailpipes aren't the primary source of emissions. The study is about PM2.5[0]. which will chiefly be tires and brake pads. Modern gasoline engines are relatively clean, outside of CO2, though diesel engines spit out a bunch of bad stuff.

How do EVs fare in this regard? Brakes are used significantly less, but the additional weight from the batteries chews through tires faster.

Tire wear on EVs has more to do with the weight of your right foot than the curb weight of the vehicle.

The high torque of EVs results in frequent wheel slippage for those eager to pull away from traffic lights quickly. Just like with high BHP ICE vehincles, smooth and gentle acceleration/deceleration will result in long tire life.
