I'm not splitting hairs here, pollution is , but I don't think the threat of an car purchase surge, REPLACING fossil fuel powered cars on the road, is the root of the problem here. Howbeit, it does knock their "" status if old, polluting tire is still used.

Reuters, "Tire-makers are under pressure to almost literally reinvent the wheel as regulators turn their scrutiny to tire pollution that is set to surge with the rise of electric vehicles (EVs)"

I stopped reading last year (after 20+ years as my go-to Western news source), it's just gone into the realm of complete bullshit.

atthenius,

@paul not just the tires. The brakes (pads) too

@atthenius @paul

Why? Our local cabbie says all his costs are down since switching to hybrid. Regenerative braking means pads and rotors need replacing far less often.

@thefathippy @atthenius

The technology is about the same across the board for brake pads, except coating is different. I'm not sure how that can change, at this point in development.

All electric and plug-in hybrid vehicles in the US have regenerative braking today. Some are more complex than others.

Even some non-electric vehicles are using regenerative braking to harness energy to charge batteries, run electrical systems, etc, to use less fossil fuel.

@paul @thefathippy @atthenius Just to add to the note on brakes —In case it isn’t clear, the pads/rotors wear out less quickly because EVs tend to do much more aggressive engine braking for regeneration. I probably use my brakes 20% as often as I did in my old ICE vehicle. That includes coming to a complete stop at lights without touching the brakes. It’s unnerving to people when they first drive one, as if the car’s a forklift.

@paul @thefathippy @atthenius I’ve driven two EVs now that had special braking modes that tried to emulate normal car deceleration by adding power as you lift the pedal in order to simulate coasting rather than going into regenerative braking. Worse for efficiency but makes people feel like they’re driving a normal car.

@paul @thefathippy @atthenius The regenerative deceleration in an EV can be strong enough that the the cars get programmed to display brake lights not just when a brake pedal is pressed but also when the accelerator is lifted past a certain point.

atthenius,

@zachnfine @paul @thefathippy The regenerative deceleration is not what I mean — it is the literal aerosols produced by brake pads when pressing the brake pedal.

LegreLeGra, that's kind of why I started my comment about pads using same technology across the board.

Thanks for the link.

It would be nice to get rid of those particles for all vehicles.

atthenius,

@paul yes— we need a new assessment of brake pad materials, indeed!

Jason844,

@paul The world needs to look at the entire manufacturing processes, EVs vs conventional cars. Steel, other metals, plastics, tires, the whole she-bang.

Also the support infrastructure, such as ⛽ gasoline production/ distribution vs generating the 🔌 electricity for the charging station.

It's not simple, it's not easy, and there is no free lunch. (i.e., your new friendly neighborhood lithium mine! ⛏️ )

@Jason844

Very true but my main editorial point was, there are 1.6 billion conventional vehicles (with tires) now vs +/-11 million EVs (with tires).

Status quo would make tires a neutral swap (esp if the EV retired the convention vehicles).

Where is the new tire apocalypse coming from?

I do hope they "reinvent the wheel."

Of course, there is one wheel manufacturing process that does help the environment during the manufacturing process, as well as easily recyclable. 😉

Jason844,

@paul Understood and agree. Tires are but one element that should be looked at and improved upon.

Oh, is that an 'old growth' wheel? 😜

That is a "Wikipedia" public domain use wheel as a dramatic punchline. :awesome:

I don't think a Chevrolet Bolt or Telsa would need a wheel that large.

However, it still is recommended to have your wheels rotated every 6000 miles or 500 termites, whichever comes first.
