How to make an EV tire that won’t pollute the environment
How to make an EV tire that won’t pollute the environment
EV tires are a source of pollution.
You're viewing a single thread.
What kind of backhanded EV misinformation bullshit is this?
Electric, gas, petrol, hydrogen, diesel, cooking oil or vodka; what you put in your car to make it go makes no difference to the tires or the wear.
From the article:
In an EV era, tires are becoming the greatest emitters of particulate matter
The point being that electric drops tailpipe emissions to zero, making tires the next target for reducing emissions.
That sentence and headline are completely wrong though. Tires already are one of the greatest emitters of particulate matter even with ICE cars in mind, because this is a general car issue and cannot really be directly resolved. An improvement would be less weight. If cars were smaller and consequently lighter, then they'd pollute less. But unfortunately we are still going the opposite direction and cars are still getting fatter and fatter, just like the people driving them.
tires need to be made of non-toxic materials. like mushroom/algae, etc.
then brake dust is next.
Brake dust is pretty well-mitigated by EVs too, on account of regenerative breaking.
That explanation is fair enough but the headline is red meat the the EV disinformation brigade.

It's funny how words affect people differently.
Not long ago, I posted a short, precisely-stated comment mentioning an observed fact that I had verified with a relevant authority. When I later checked in, I was surprised to find someone accusing me of spreading misinformation, and my comment removed by a moderator. It was clear that my accuser had badly misinterpreted my words. He refused to admit it or accept clarification. (And the mod had already acted, rashly.)
I re-checked what I had written about twenty times over the course of the day. There was nothing there to support the accusation. My best guess is that my phrasing or the subject matter might have touched on rough emotions from a bad experience, leading him to see what he expected to see instead of what I wrote, and triggering attack mode.
Communicating well really is complicated. It takes work on both sides, and can quickly turn into a bad time if it goes off the rails.
Because of this, I've been making an effort to read (and re-read) charitably, especially with people I don't know well.
That’s a terrible thing to say!
…Only joking.
I tried to buy an EV for my parents a couple of weeks ago and the dealer had the EV misinformation playbook memorised and tried to convince us that EVs were a fad and that should get a hybrid until Hydrogen takes over.
I’ve decided that whenever I see these common myths, I’m not going to just let the misinformation go unquestioned.
In this case I think specifically focusing on EVs will generate more clicks for article writers, but it does also feed a common anti-EV narrative that they are somehow worse than ICE cars because of tire wear, which is not true.
I do see the other side that the tires being developed are specifically looking at EV owners, so this is a tough one to get the balance right on, but I do still think the headline is written to stir trouble and generate clicks.
One thing is certain, America needs to stop buying so many trucks!
It does. EVs are much heavier due to battery weight and have more power and torque. Which all results in more tire wear.
2023 top 5 vehicles sold in USA and weight:
1 - Ford F-150 4069-5697lbs
2 - Chevrolet Silverado 4400-6947lbs
3 - Ram pickup 4765-6440lbs
4 - Toyota RAV4 3370lbs
5 - Tesla Model Y 4416lbs
Looks like the only electric on the list is below the average weight. We don’t have these conversations about the trucks.
That's a list of a bunch of trucks compared to a midsized SUV, so you're kind of proving yourself wrong. Cars are split into weight classes, so a comparison that doesn't acknowledge that isn't very useful. A EV Sedan is on average much heavier than an ICE sedan.
No one's saying ICE vehicles are better for the environment than EVs
Those are the most sold vehicles in the US, when you have heavy EV’s in the top slots you can say that heavy ev’s are a problem… until then it’s what you are buying is causing the problem.
Just because something isn't the biggest problem doesn't mean it's not a problem worth talking about.
I agree entirely, but the title of this post suggests that EVs are the problem, but actually it’s heavy vehicles.
Additionally when we say “problem”, particulate pollution from vehicles is 99.9% a diesel problem, and 0.1% a tire problem. (Not actual statistics but let me know how wrong I am with the actual stat)
No one’s saying ICE vehicles are better for the environment than EVs
I think it's possible for a diesel vehicle running on 100% biodiesel made from waste oil to be. The problem there is that there isn't enough of that sort of fuel to go around as long as cities keep getting designed to keep people car-dependent.
Trucks are a whole other issue into themselves, though. Not just the tire wear, but their terrible fuel economy.
7,000 lbs, fucking hell. Who needs such a massive vehicle??
Fragile egoes
Well there are contractors who need to tow heavy machinery around, so about 0.01% of the people that buy them need them.
Wow, that's an impressive list of amateur tanks. Do they also sell real cars in the US? (Rhetorical question)
Jesus christ that is appaling. What stupid fucking vehicles.
This is false. They aren't really that much heavier, 1k lb or so. It's not the weight that tears up tires it's the instant and 100% torque when you hit the accelerator. If you go easy on the launches your tires will last longer.
Hey man, it's got nothing to do with them being heavier, it IS about how that weight is distributed differently. You've mispoken and now everyone is latched on to something that isn't true about something that is true.
EV tires are made from different compounds then truck and car tires which causes them to wear ~20% faster.
-
EVs have instant torque delivery, which can put more strain on the tires during acceleration. Therefore, they need EV tires that can handle the increased force and extra weight.
-
Electric vehicles have heavy battery packs, affecting the overall weight distribution. This can impact tire wear, so EV tires are designed to carry and distribute the extra weight effectively.
-
EV tires are engineered to have lower rolling resistance. These tires reduce the energy required to move the vehicle, resulting in better range and longer battery life.
-
Most EVs use regenerative braking systems, which recover energy during braking. EV tires offer better traction and grip, enhancing the effectiveness of regenerative braking.
-
Electric vehicles are generally quieter than traditional ICE vehicles. To complement this characteristic, EV tires are built to reduce road noise and vibrations, providing a quieter and more comfortable ride

Agreed. Here's example of properly-engieneered EV for city in use:

I mean I dunno about you but where I live it gets really fucking hot. And sometimes it rains.
Blah, blah, blah -- quit being such a damn wimp!
The high today in my city is 97 °F and guess what: I get on my e-bike instead of in my car anyway! It is really not even slightly as big of a deal as you're trying to make it out to be.

Rain, snow, forest fires, from -25°C to +38°C. In one word: Moscow.

No idea why +38 is cool for you.
You're getting down voted but you're right. I don't think people realize that most tires are now made from synthetic rubber, AKA plastic.
Also someone tried to disprove you by posting a list with ICE trucks being as heavy as EV cars. Like what? Of course trucks are heavier. EV Trucks are even heavier than that and an EV subcompact will be much heavier than an ICE compact. Also everyone is talking about how trucks and SUVs are getting heavier and bigger. So not sure what they mean by "we never talk about this with trucks!"
That is a list of the most sold vehicles in the US. Where are the people lining up to say the ICE trucks that are so popular are causing all this tire pollution?
but you're right. I don't think people realize that most tires are now made from synthetic rubber, AKA plastic.
This is not what was said. Nobody said they aren't.
posting a list with ICE trucks being as heavy as EV cars
Link? Here there is only list of most sold cars.
It’s dumb, but I think the author was trying to say, “we have an emissions solution for the motor, and now it’s worth exploring where else we need to address emissions for motor vehicles.”
