And not a distinguishing factor of ICE vehicles

EV have far more tire wear because they are heavier and also probably from regenerative braking

  • Why would regenerative braking emit more particulates? It’s no harder on tires than braking mechanically but doesn’t abrade the pads or rotors.

  • >> EV have far more tire wear because they are heavier

    Is this true?

    If an EV were 30% heavier than an ICE, would it produce 30% more tyre wear emissions? Or would it produce more or less than 30%? Is the primary factor in tyre wear weight and is the relationship linear?

    The types of tyres appear to be quite different, the EVs seem to have smaller contact patches (narrower wheels) and they're made of different "less grippy" compounds that drag less. Does this change the equation at all?
