EV use of Magnetic Braking reduce brake wear by alot . With One pedal driving in city not using brakes at all

I almost never use breaks. It is a game for me, so I'm conscious of any time I have to use them. On the other hand, EVs unfortunately pollute more with tire particles (thanks to both higher torque - especially from 0 - and higher average mass).

  > EVs unfortunately pollute more with tire particles (thanks to both higher torque - especially from 0 - and higher average mass). I wonder how much the higher torque of EVs is a real issue? Although they have the potential to do more aggressive acceleration and produce more tyre pollution, the Teslas I see leaving traffic stops seem to be accelerating the same as ICEs.

    EVs also tend to be heavier than their ICE counterparts.

      > EVs also tend to be heavier than their ICE counterparts. As the parent comment said - but I was questioning about whether increased torque has an actual impact on tyre wear.

        Indeed I wonder at “normal” speeds (not racing say) does torque matter or is wear dominated by total miles driven? If I zoom to my destination do my tyres wear substantially more than if I take a more sedate approach? (Certainly when I was young and dumb my clutch wore more when I went dashing about).

        yes

        In my experience, someone who is new to EVs will tend to do a lot of short, fast accelerations to explore how the vehicle performance. That happens mostly in the early stages of using an EV and after a while they settle in to a more normal (ICEV similar) acceleration pattern.

        I’ve driven an ev for the last 3 years (over 100k kms) and find my tires last about half as long. So yes, it has a big impact.

  Do you have hard numbers on the tire particle claim? We have anecdotes of Tesla owners saying they go through tires more often. But I’ve also heard car fleet owners with both EVs and ICE saying they see no difference between them. So I’m inclined to think this is entirely dependent on the specific EV. You can get an EV without significantly more weight than an equivalent ICE, and you can drive them in ECO mode where the torque curve is extremely gentle. I don’t see any reason why you’d have more tire particles in that scenario. I think there are pathways to have less tire wear on EVs than with today’s ICE vehicles. Batteries with higher energy density would obviously help, but I think there are things you could do with the accurate control you have over the torque on the wheels, or making true all wheel drive with torque vectoring more common.

    I have a Ford Focus EV - still haven't replaced my brake pads - 7 years strong. Finally replaced my first set of tires last winter.
