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.
I'm not sure I can agree with this. I have 2 EVs, and the tire looks almost brand new after like 10k miles. I think the driving habits matter more than whether the car is EV or not.

Wow. Well, I like that the people that think like this also probably live I places where you are actually driving a coal powered car. Like the clowns in Hawaii that have extra subsidies for EVs… their power comes directly from burning crude oil. I’m an automotive EE, and and the truth about EVs is in a rush to push them out the door, the media and politicians have set the tech back at least a decade by pretending it…
Well, most of us don't have a plan B if the Earth is wrecked by pollution, but I guess if you beg Musk hard enough, he might invite you to Mars. We can either do drastic things now, or desperate things later.
Pollution and environmental destruction are big problems, but there are no remotely likely scenarios where the Earth "is wrecked by pollution" and a HN reader would need to question the viability of remaining on the planet.

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.
Secondly, I rented an EV for a week and by the end of it actually preferred the strong regen setting. It was convenient in stop-start traffic, and on a twisty road, you could use it to tighten the nose as you entered the corner.

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.
Some of the lowest rolling resistance tires also last 80k+ miles. It's not a tradeoff in the way you're claiming.
We should obviously ban combustion engine cars, at least starting with cities. I can’t think of a single clearer win for air quality.
Make streets narrower. Reduce parking. Return road infrastructure in favor of walkability, green areas, and reducing urban heat islands.

It's related to vehicle weight, electric cars can be significantly heavier.
My understanding is a model X is 20% heavier than a similar size mid-range suv like a telluride, which I would consider the same size SUV. The Model X's curb weight ranges from 5,148 lbs to 5,531 lbs, while the Telluride's curb weight falls between 4,112 lbs and 4,482 lbs.

I assumed instead they were soft compound tires with a low treadwear number. Nice for "sport" driving but they wear very quickly.
All the people claiming EVs wear tires faster probably don't have the slightest idea that tires even have treadwear ratings. That coupled with the total uselessness of personal anecdotes... Performance oriented EVs, just like performance oriented ICE cars , are going to have softer, stickier tires that wear faster.
brtkwr has a Kia Niro, not a Taycan. It's not a performance vehicle.
That said, I agree he's likely got tires with shit longevity.

If all of us renters were forced to convert to electric there’d never be an open charger in any city again for the next five years, because no landlord will voluntarily afford that cost, and no municipal region can pass a ballot measure to afford that cost. California’s impending ban of combustion car sales hinges wholly on a magical DC-charging network that doesn’t exist in U.S. cities yet (i.e. at parking meters),…
Other countries have figured this out. Norway in particular. Working transportation models exist and this country has the funds to make it happen. However because of American Exceptionalism, we have very limited options.

Just normal driving, it wasn’t quite so bad on our previous car which was a Nissan Leaf (with 30kWh battery) but our current Kia Niro just has a lot bigger batter (64kWh) and it is a lot heavier I suppose, the tyres just don’t seem to last as long. I’m pretty sure I’m using summer tyres all year round (I live in the UK) this was recommended by the dealer
remember, your regenerative braking comes at cost of tire life. If driving Tesla, you can reduce the regenerative breaking from Maximum setting to Medium. this will reduce regeneration and will increase the "breaking distance" when you just let go of accelerator pedal. but it will increase your tire life significantly. also make sure to buy the "commuter tire" models - tires with high mileage warranty (50k miles+) an…
No, it doesn’t. The tires don’t care if it’s the car’s motor slowing things down, or some friction material grabbing a disc.
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.

Hybrid makers just don't really care about that.
