Electric cars produce less brake dust pollution than combustion-engine cars (modernengineeringmarvels.com)

I went to get new tires on my truck last month. 3 of the 5 bays at the tire shop had teslas getting new shoes. I asked the shop owner and he said EVs eat tires. Like 9-12 months max lifespan, great for business. I couldn't believe it but I've always heard there's exponential wear on tires relative to weight.

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.

Good to have more data points and evidence, but this seems extremely well established by now?

Zero tailpipe emissions, drastically removed brake dust, slightly higher tire wear (due to weight), but much better overall than ICE.

We should obviously ban combustion engine cars, at least starting with cities. I can’t think of a single clearer win for air quality.

I pick up a bad screw every year from careless Ute drivers with leaky toolboxes and have to throw 1-2 tyres in the bin.

Tyre wear isn't that important to me.

lol no shit sherlock.

I've owned a Pirus (hybrid), Camry Hybrid and now a Rav4 Hybrid plus a MG4 EV.

The rav and MG4 are too new to count, but the other two I owned for about 10-13 years each.. we NEVER needed to change the brake pads.

Not once.

If you're having to change the brake pads on a car like this, you're a leadfoot with no core strength issues :-P

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.

Heavier cars with more torque at the wheels means more tyre dust.

Who knew that a vehicle with two brake systems would use the traditional one less than vehicles with only that type!?

But they burn through tires much faster due to the battery packs. All that tire friction has to go somewhere right?

Ban the stop and go hell of rush hour. Cars rolling at freeway speed without stopping pollute way less than drivers stuck behind idiots who can't just go forward down the road at the speed limit.

The human suffering and ecological impact reduced if only there would be a focus on enforcing speed minimums...

So let's make cleaner brakes for combustion-engine cars.

55k miles on my Leaf. Not even halfway through the first set of brake pads. I cannot say the same thing about the tires.

There are ceramic brakes that produce very little particulate matter by comparison to semi-metallic. The only downside is performance can degrade more in extreme driving conditions (sustained racing with heavy braking). For a daily driver, it's a quieter and cleaner material.

> The EIT Urban Mobility report also refers to the bigger picture: moving commuters out of private cars and into public transport, cycling, or walking can achieve up to five times more reduction in non-exhaust emissions than individual electrification.

And this is just one the many nuisances produce by cars.

Electric cars do not massively reduce almost any of the pollution produced by cars.

We have to reduce the automobile fleet by at least 95% to solve all the nuisances produces by cars.

A well known fact by Brembo, one of the biggest brakes producers in the world, which has been working for years to find new products and new markets, preparing for the time when a lot more EVs will be on the road.

Brake pads are small parts that last for years. It is nothing compared to the number of tankfuls of gas that an ICE car goes through over the lifetime of its brakes.

This is like the March of Dimes syndrome. We got rid of exhaust with electric cars, but the cars-are-bad activists continue to exist and need something to gripe about.

On my non EV car I seldom use the break unless in an emergency or I have to come to a full stop.

I always use the cruise control to decelerate and accelerate. Anyone else has that habit?

[dead]

Has anyone modeled how much excess cement and asphalt pollution is generated by having a tiny car weigh as much as a giant truck? Or the water usage of increased lithium mining?

EVs are like an inferior product being shoved down everyone's throat when consumer cars don't even account for the most emissions globally.

continuation of EV propaganda, which are much heavier cars.

Does this apply to fixies then as well? I might reignite my use of one in a city vs traditional bike if so ...!

> Gains, however, are not equitable. Low-income neighborhoods, which often endure the highest pollution impacts, have seen slower EV uptake, demonstrating the necessity of access to clean transport on an equitable basis.

Air quality tier list:

S-tier: African/American/Australasian countries that were never discovered by the West, and have no energy sources (hypothetical)

B-tier: Western countries and similar (e.g. Japan), and those who've had a resource that they've traded for Western advances (e.g. Asia/Middle East) that can afford nuclear and renewables

D-tier: Sub-Saharan African/South American countries that now have energy needs but are burning coal or diesel to meet them

EVs tend to be heavier that ICE vehicles, I’m skeptical of this conclusion.

I’m not sure how you get more tire wear but less brake dust.

the brake needs a brand new design for EV... as of now it's used so little I kind of fear when I need it it's not going to be performant. It's not simply not engineered for current EV use case where it's touched every once in a while, I think it can go weeks without being used. However manufacturers don't have any incentive to blend it with regen from time to time, as to get it up to temperature requires a LOT of braking, which reduces the mileage/efficiency. Even Volvo recently had a recall[1] over regen braking bug, it looks like brake-by-wire system where software have control over blending brake, and decides in this case to not engage physical brakes at all even when user input suggests more braking. We just need a new brake system that can stay performant without being used at all for a long time and won't rust or jam [1] https://www.caranddriver.com/news/a65464238/volvo-brake-fail...
