Here’s something the Biden administration and CA Gov. Gavin Newsom haven’t talked about: electric cars actually emit more soot and particulate matter than their gas-powered counterparts—because of their tires. //

the WSJ writers argue that tire wear from the far-heavier EVs is more contaminating:

Where do most particulate emissions attributed to cars come from? California speaks as if their primary source is the tailpipe. That was true in the past. But today most vehicle-related particulate matter comes from tire wear. Cars are heavy, and as their tires rub against the road, they degrade and release tiny, often toxic particles. According to measurements by an emission-analytics firm, in gasoline cars equipped with a particle filter, airborne tire-wear emissions are more than 400 times as great as direct exhaust particulate emissions.
