The average weight of all cars has been increasing. But there has been particular debate over whether battery electric vehicles (BEVs), which are heavier than conventional cars and can have greater wheel torque, may lead to more tyre particles being produced. Molden said it would depend on driving style, with gentle EV drivers producing fewer particles than fossil-fuelled cars driven badly, though on average he expected slightly higher tyre particles from BEVs.
More here, in "Car tyres produce vastly more particle pollution than exhausts, tests show".
Meanwhile, the great Scotty Kilmer was all over this like white on rice a couple of days ago:
