Yeah, make them out of metal, that rolls on metal roads. And those metal tires can carry a ton more weight, so put a lot of people in them who are going the same way.
Oh right, we already have those.
Noooo, you don’t get it, bro. Just one more lane, please. I promise, it will be better than last time. One more lane, that’s all we need. I’m begging you, please.
I’m on my knees here. One more lane, just one more! This time it will be different, I swear. We won’t have traffic jams, I promise! Just one more lane and we’ll be free.
Come on, man, think of the children. Just one more lane. I’m begging you. For the love of liberty, just one more lane!
Adam, is that you? 😉
Hah!
¿Por qué no los dos?
Any economical ways to run farms on rail? A lot of the roads where I have lived were just built and paid for by famers to move equipment between pay dirt and make their way to town occasionally
Did tech bros just reinvent the concept of trains?
Do we? Sounds too futuristic. Not as futuristic as linking these megacars together.
Hot take: tire particulates are a conservative anti-EV talking point. “My V8 mustang weighs less than an EV, therefore its better on pollution than a EV because tire particulates”. Totally disregarding the impact of tailpipe emissions.
It is also a vaild anti-car talking point.
!fuckcars@lemmy.world material
I think it’s just reminding people that EVs aren’t a panacea to all our issues with transportation, and they actually exacerbates at least one of those issues. This is while we know there are better solutions for >90% of our personal transportation with public transportation, bicycling, walking, micro-mobility, etc. Moving one or two people around with a multi-tonne machine is insanely inefficient!
Exacerbate = the rare minerals issue?
No it’s not, because conservatives don’t think micro plastics are a problem. Pretty soon there will be truck bros making tiktoks competing to see how quickly they can destroy a set of tires just to “trigger the libs”.
Anecdotally, so far I’ve noticed cars getting louder
They’re loud because of safety reasons!! /s
I saw a thing on some US people welding fucking whistles in their car’s exhausts so that they could annoy as many people as possible. Apparently it’s legal in some places there.
The whistles go woooooo!
One person I know claimed to have run calculations, and found that the tire dust alone was putting out more pollution than the tires and tailpipe of the average gas car. Idk where they got their numbers or how that could work out, since the average gas car in America is a large truck.
It seems pretty obvious, but also, it would be nice to see improvements in this area.
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 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’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.”
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.
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.
EVs are much heavier due to battery weight
That’s not inherently true. It’s most true for grossly oversized and inefficient EVs. Which is unfortunately most of what they build today.
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. So something with a cabin and air conditioning is mandatory. I’m a big fan of electric micro-cars.

Rain, snow, forest fires, from -25°C to +38°C. In one word: Moscow.
Cool?
No idea why +38 is cool for you.
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

Now how about using iron tires on iron road? And using public transport?
Fuck yeah, public transit - Right in my veins, lets go.
But for right now, there is ZERO public transit infrastructure where I live, which is only about 20-30 minutes to a medium-sized city’s downtown. And when I say ZERO, I mean ZERO. We don’t even have busses here. No trains. NOTHING. We don’t even have sidewalks on most roads - if you want to walk, you’re literally walking in the road. I used to ride a bike to work a long time ago - I can’t even count the number of times I’ve had shit thrown at me by shitbag rednecks as they zoomed past in their lifted pickup trucks.
The local governments’ answer to all this is “If you don’t have a car, fuck you.” Cars are literally the only option. If you don’t have a car or a driver’s license, you better find somebody who does and give them gas money, or consign yourself to paying for Uber/Lyft anytime you want to go anywhere. It’s straight-up dangerous to travel any other way around here.
I hope it will get better for you.
I support public transport but I really don’t know how to convince people. I live in North America.
whispering more trains
Trains are the best electric vehicles
Sometimes too many trains is a thing.
Do you have an example of this?
Some parts of London. I used to live in a building next to three sets of railways: the tube, regular intercity and express/higher speed intercity. That’s a bit too much railway outside the window. And that’s not even the worst location, in the New Cross area some residential buildings are sandwiched between railways on all four sides.
Don’t get me wrong, I love trains in London, so many trains means I don’t need a car, but London has the oldest railway infrastructure in the world and the way they were built in the 19th century makes some areas a total disaster today.
On the other hand, riding a DLR train through a skyscraper is bloody epic!
So this big breakthrough in tire technology is . . . making them harder and reducing their grip?
EV are much heavier than petrol cars, maybe the offset weight will help regain some grip? Normal tires wear out so fast on EVs.
That extra weight will also mean that more force is required to accelerate and change directions.
The nimbleness of a vehicle can be expressed as the ratio:
(Tire Contact Area * Tire Stickiness) / Vehicle Mass
Increasing the vehicle’s mass while making the tires harder will lead to longer breaking distances and will cause a vehicle to understeer at lower speeds.
Username checks out.
it sounds like these wheels need to be much larger to offset the lower grip. Wonder how that affects the environment.
Just staple Post-Its to regular tyres.
the staples will tear up roads and tires
maybe the offset weight will help regain some grip?
…what? LOL The added weight also offsets the grip…
Pls don’t make them soy-based or some human food based, rodents and other small critters with teeth will gnaw at them like what happens with engine hoses…
And now to make lighter EVs that don’t wear on the road so much.
Done:
And now to make lighter EVs that don’t wear on the road so much.
Tesla Model 3 Long Range (as an example) weighs in at 4,034 lbs, while the Ford F150 is 4,391 to 5,863 lbs.
Shouldn’t we start with the majority of ICE vehicles which already weigh the same or more than EVs?
A model 3 to an f150 is absolutely apples and oranges.
Seriously. We are talking about tire tread compared to weight. Both use multiple sizes of tire depending on the year/model. There are a few that overlap in diameter to get the closest to comparison but they still have a very different width. We are talking about a 235/35R18 vs a 235/75R18. That is a huge difference in wall height/aspect ratio and changes how the tire gives under power. Those numbers massively change depending on model as well. Something like an f150 raptor could have a 315/70R17, almost a foot wide. So comparing just the weight and saying they are close enough is far from a fair comparison.
A model 3 to an f150 is absolutely apples and oranges.
Seriously. We are talking about tire tread compared to weight.
Are we? I thought we were talking about tire particulate pollution. Why have I never heard the conversation raised that truck tire pollution is a problem? Why is it only EVs that its suddenly an issue?
I keep fingers crossed for wireless charging built in road 🤷♂️
Wireless charging is very inefficient, I don’t see that happening unless some new tech gets invented.
Sure, it’s not ideal but in the grand scheme it might be the future as it’d change many aspects starting with battery sizes. It might be a failure as well, due to politics and economics, who knows.
Wireless charging: The roads where electric vehicles never need to plug in
Yeah, could be nice. You should check out Aptera, it’s kinda sorta almost the same thing. Up to 40 miles of charge per day from solar.
Make tires out of ground up bureaucrats, they’re organic and biodegradable, and there’s an endless supply of them.
First of all, biodegradable doesn’t mean what you think it means. For example, PLA plastic is biodegradable - good luck trying to compost it at home.
Second, source material doesn’t mean that the end result will be biodegradable as well. You will need to polymerise them and you’ll end up with the same plastic and rubber as if you’d use oil. PLA is an example again! It’s made from lactic acid, which you can and do eat. You can also eat pure PLA, but again - it’s not compostable.
