How is tire wear related to the method of power? It could be a steam engine for all it mattered. Accelerating and decelerating, in regards to the tire, don't care what is causing the force.

To be fair EV's can have some very high initial torque delivery, and are heavy = tyre shredding beasts. I know I know, people aren't supposed to be taking off from every light at full chat, but, given the capability some people can't help themselves.

The biggest problem for new EV drivers, in my view, is that EVs generally have extremely good traction control systems that prevent chirping due to the ability to cut back power to the motors much more quickly than you can with a gas engine.

What this means is that you can push tires to the absolute limit and not chirp them (which, is best for traction anyways) which absolutely roasts them. Most people associate chirp = too fast, but with EVs you can never hear a chirp even when you stomp on the accelerator so they might think everything is ok.

Nobody should be shredding a set of tires in 10k miles in any EV unless they’re super low tread wear (poor tire choice, hard to do that bad), there’s an issue with the car suspension, or they’re just being idiots.

You could possibly have come to an arrangement about getting a 50 Amp (think dryer plug) hookup in the garage and provided your own charger. Also depending on your driving patterns a trickle charger in a 20 Amp socket may have worked for you as well. Mine takes about 48 hours for a full charge on the trickle charger.

There's no garage, and the only driveway-facing outlet is at the front door - opposite where my parking spot is allocated (an extension cord would have to go under/through the landlord's cars.) I have to drive 60km to work every day. Only laws (accommodate EVs and/or WFH) or spending time sitting at a gas station will help me here. No landlord is interested in accommodating an EV unless it's a net benefit to them (an…

Sorry to hear that.

I suppose the same should apply to hybrid cars, which outnumber pure EVs significantly [1]. The effect comes from converting the kinetic energy back to the battery charge via generation instead of wasting it via friction, which is the whole point of hybrids.

To some extent, but not really. Effectiveness of regenerative braking depends on having an extremely large battery that can sink enough current to stop the car. An EV can do that, hybrids at best help the brakes out some. You just can't charge the battery fast enough doing anything but a very slow rolling stop. My model Y can effect a very reasonable stop in traffic without touching the brake pedal except to hold the…

I test drove an EV and the regenerative braking was difficult to get used to. You have to constantly ride the gas pedal. I would buy an EV if it weren't for this feature.

We finally gave up our Prius after 12 years, and we never changed the brakes once. The brakes were just peeking into the yellow on its last service upgrade. I was really impressed with how well the "normal" hybrid could take advantage of regenerative breaking, honestly.

I first changed the brakes on my Mitsubishi Space Star (combustion) after 13 years. It is a small car, less than 1000kg, so there is little for the brakes to do. If we produced more percentage of small cars, many environmental risks would be reduced. And btw.: The tires are now 19 years old and still good (less weight, less abrasion!).

There are three things at play here: - evs have a reputation for fast acceleration, and many drivers use it. More wear. - evs are heavy due to large batteries trying to match ICE range. More wear. - evs often come with low friction tires to improve range, they wear faster The second two issues should gradually go away as battery (and charging) tech improves.

Low friction tires wear slower, not faster, on account of being ... Low friction. Friction is what wears tires.

Sure, but how big is your contact patch? They’re low friction for a reason.

You can toggle off regen braking on most EVs

It is the low temperature performance that make most EV impractical. A Tesla power pack heater means the charge will be completely depleted if left outdoors for more than a week in winter. EV are meant for people that live in 4'C to 42'C weather, and have excess capacity on their solar installations. Everyone else is getting subsidized by their neighbors paying for excess electrical capacity. =3

Someone needs to tell all those people in Norway.

NY and Chicago are a little closer... =3

Some EVs allow different levels of regenerative braking to be selected. The Hyundai/Kia E-GMP-based cars have level 0-3 plus a 1-pedal mode, and also an "auto" mode that slows down more based on radar proximity to the car ahead.

We have owned 4 EVs and each allow you to configure the regen braking strength. You'll need another reason to not buy one.

An an EV owner, I can testify that the tyre wear more than makes up for the reduction in brake dust. I’ve had to change tyres every 10K miles.

The article says that even including tire and road wear, EVs generate 38% less particulate pollution than ICE cars before considering the lack of tailpipe emissions.
