While there’s no doubt tires are bad for the environment, a quarter of all microplastics seems a lot, especially since plastic is everywhere. Gladly there’s a source for that claim, a link to tireindustryproject’s FAQ… Claiming that this number is a gross overestimation. What the fuck is this article? Is it supposed to be satire or something?
Bear in mind that the denominator is plastic pollution. Most plastic waste does not directly pollute the environment. If it is not recycled then it goes to landfills or incineration. Not ideal, but at least the damage is contained. (The bulk of ocean plastic comes from the rivers of poor countries without proper waste management.)
The issue with tyre microplastics is that it’s all but impossible to channel the waste. It’s the same with synthetic fabric: just washing it creates pollution that’s really hard to control.
So then isn’t it 1/4 of a meaningless number? It seems like the specific impacts mentioned in the article (zinc,6PPD) are more relevant.
I’ve seen a similar number in a lot of proper scientific sources, so this article may be bunk, but the number is correct I think.
For example this article: https://doi.org/10.1016/j.scitotenv.2024.171003 They claim 27,26% in China.
And this article: https://www.rivm.nl/bibliotheek/rapporten/2024-0106.pdf They claim 24.88% in the EU and state it’s among the biggest if not the biggest contributor to microplastics.
I’m all for debunking stuff, but about a quarter seems to be the currently accepted quantity to the best of our abilities to measure.
There is a bit of confusion between the amount tyres contribute into the ocean, how much into the ocean and waterways and how much in the environment as a whole. A lot of it ends up in the soil, so it doesn’t contribute to plastics in the water, but still in the environment.
That was an interesting read. I guess tyre fragments (and industrial pellets) are just way bigger than the other big offenders, which would explain why they represent such a huge portion of the total mass, and why they are filtered out “easily”. Overall it seems to me that we really need to categorize the different microplastics better, as the current definition (anything plastic 5mm and under) seems a bit too large, and with all the mix ups, you can always blame something else.
Wow, now imagine what tractor tires are doing to the fields we grow our food in. Plus the exhaust and tires deposit heavy metals. I have been bitching about this for years. We need drone fleets in fields and to ban tires and exhaust in fields.
Where have all the steel wheels gone?
They went around smaller steel wheels:
I wish it was pure iron dust wearing off that steel, but no. The flying drone idea seems good, but for harvesting?
Exhaust gas is poison.
The relatively high amount of metal contents emitted from diesel engines strongly suggests that the measurement on the control of metal contents in diesel fuel should be taken in the future.
https://www.sciencedirect.com/science/article/abs/pii/S1352231003006241
As, Hg and Se exhaust emissions were dominated by fuel combustion while Cd, Cr, Cu, Ni, Pb, and Zn exhaust emissions were dominated by lubricant oil combustion.

I think we could eventually do drone fleets for harvesting too, yes. It should be the new standard so we stop poisoning ourselves.
The tires aren’t breaking down like they do on asphalt. Not the same.
I come from farmers. They are still breaking down and still an issue. They also cause soil compaction. Anyone familiar with farming understands that tractors aren’t good for soil
That we know of.
Vulcanized RUBBER tyres shed PLASTIC microparticles … hmmmm something sounds very rubbery and not at all plasticky… i truly wonder what it could be …hmmmm…
Edit: “Is rubber considered a plastic? Although materials such as rubber, textiles, adhesives, and paint may in some cases meet this definition, they are not considered plastics.”
Here is a Scientific study MIS-CONSTRUING Rubber as a Plastic AND MAKING ASSUMPTIONS WITHOUT PROPER EXPLANATIONS !!!
https://pmc.ncbi.nlm.nih.gov/articles/PMC5664766/
This is the problem with Scientific studies, Media, Reporting and bunch of people running with studies that make a lot of FALSE ASSUMPTIONS WITHOUT TELLING YOU THE FULL FUCKING STORY.

ah, but randos online know the real story. The Caplocks only adds to your authenticity. Look, you’re trying to ague about semantics to discredit concerns about microplastics getting in people’s blood streams. Within the context of micro particials, there’s really not much difference between “rubber” and “plastic” as what makes them unique to each other is their properties when bonded in large forms. Maybe it’s harmless or maybe it’s this generation’s lead poisons, toxoplasmosis, or aspectos. Aspectos, which by the way, is perfectly natural, but still dangerous to humans. Something I have to remind people when they talk about corn oil based plastics. The half life on PLA may be shorter, but research is still being done on how quickly harm happens and what levels harm can occur.
Tyres are made from synthetic rubbers which are plastics.
The study linked in the article also says that microplastic and rubber are different. As far as I understood it, they also quoted it wrong.
Exactly. We need more and better peer-reviewed and vetted studies. Is rubber pollution exactly same as micro-plastics? Or is it 80% the same effects? Is it the same effects due to the same chemicals? Is it similar due to the same processes and not necessarily the end-product material ? Many many questions that people don’t seem to understand and just blindly trust whatever some “latest study shows …” bullshit that has been going on for a very long time.
Rubber can mean both, natural rubber from specific trees, or synthetic rubber, which is made out of plastics.
Again there is a difference even when you say synthetic rubber,
DO NOT MIX AND CONFUSE RUBBER and PLASTIC.
Rubber === mixture of ISOPRENE and ELASTOMERE polymers ( naturally occurring from Latex/rubber trees but 50% naturally produced and 50% synthetically produced from petrochemicals)
Plastic === mixture of various Ethyl,Propyl,Poly-Propyl Polymers mainly derived synthetically from petrochemical sources ( may or may not be combined with elastomere for rubberized properties).
So MOST MODERN Industrial processes are DIRTY and HEAVILY POLLUTING.
Dont confuse Rubber and Plastic manufacturing and lump it into a single problem unless and until you have definitive and REPRODUCIBLE PROOF THAT PROBLEMS ARE COMMON TO BOTH.
Are you a bot? lol
This is too incoherent for even a bot.
Is that your only retort to being shut down with logic? I love the spirit of this sub but the people in here are so unbearable
Is all of your clothing natural fibers? I guarantee you are shedding pounds of microplastics into the environment every year personally
Got a goretex jacket? You are killing the earth with PFAs
Shut down with logic? My entire comment was about differentiating between natural and synthetic rubbers and he wrote an entire wall of text about how I have to differentiate between natural and synthetic rubbers.
And yes, except for a couple jackets, which I don’t really wash at all, all my clothes, bed sheets etc. are out of 100% cotton. Always have been. My top level comment in this very thread is literally me calling out synthetic textiles. Any other things you want to project onto me?
Imagine things being made of multiple components and not one pure component. /s
Imagine confusing Tigers and Lions and claiming BIG CAT micro-pussies are causing problems all over the world!!!
Tigers are different and Lions are different. They are big cats but different species have different habitats and habits.
So dont mix Plastics and Rubbers when they are chemically different and may have different manufacturing processes.
Was that really hard to understand ?
I worked at a tire factory. Half the rubber used in tires is synthetic rubber, which is made from plastic. Your car tires are not made from 100% natural rubber from a tree.
Synthetic rubber is not plastic. It is from petrochemicals but not the same chemical substance.
A plastic is just a material made from polymers, you are the one adding artificial limitations on what polymers can be used. The belts in tires use both nylon and polyester which are both plastics by anyone’s definition. So even by your strict definition, tires are made up, at least in part, by plastic.
Was that really hard to understand ?
… umm, yes. I have literally no idea what you’re talking about.
Microrubbers sounds like condoms for guys with unfortunate situations in their pants though
Were guys with an unfortunate situation, but no kids or STIs!
Sure we might have microplastics and microrubbers inside our brains and balls.
Maybe we need a new study of “Forever chemicals” and “Short-term chemicals” and “Long-lived chemicals” redefined and not use confusing terms like “microplastics” for anything polymerised. DNA is a polymer but we dont call people microplastics.
hi HOW ARE you TODAY?
i’m pretty GOOD MYSELF!!111!!!
I TOO like to RANDOMLY SWITCH TO upper case.
I HOPE YOU RECOVER SOON!
Daddy I’m so sorry microplastics in your bloodstream are causing your untimely demise…
mic
miiii
Yes Daddy?
they’re MICRO rubbers you ignorant IDIOT
Thanks for the link that argues against your rant. I guess you could salvage it some by comparing the numbers and claiming the plastic component is lower than the main article’s numbers in contribution. It would be awkward though if you find out they already separated those number in their math. It also doesn’t change the point that a huge amount of pollution in the form of tire wear occurs constantly and isn’t going away anytime soon.
If only there was a highly efficient mode of transporting people that didn’t use tires. Ah well, nothing can be done I guess.

Yes, imagine if there was a fast and safe way of transport. Something like made to run on steel bars in order to reduce friction. I don’t know. I’m just imagining, I watch too much science fiction.
My city’s metro system uses rubber tyres, :(
To be fair, the most efficient mode of transportation is cycling by far. I wonder if bike tires also contribute to this.
I’m sure they do but it will be way less.
The wear rate should be proportional to the weight of the system (car plus cargo and passsengers, bike plus cargo and riders), maybe with some correction factors for things that affect wear rate like knobbiness.
Since bikes weigh a couple orders of magnitude less on average, the amount of tire wear material should also be a couple orders of magnitude less.
Edit: other lemmyer said wear is proportional to weight to the 4th power and that may be correct. I vaguely recall that from school now that they mentioned it.
Assuming the material properties and physical design of the two tire types is identical, maybe
Doesn’t speed/acceleration affect it? If that is the case, that’s another pro for bikes.
should be proportional to the weight of the system
It’s that really true? Wear to the roads is proportional to the fourth power of axle weight so I would never have predicted a linear relationship.
Exponential relationships are still proportional.
No they are not. That’s not what it means.
https://en.m.wikipedia.org/wiki/Proportionality_(mathematics)
Bikes cause thousands of times less damage to streets so I wouldn’t be surprised if they also wear less.
Good point! Also much less weight.
And the size of bike tires is way less than a car tire.
They do
so, basically, drive on three wheels and the problem’s solved?
If all you bike owners drove unicycles we wouldn’t be in this mess

Brake pads are also moving away from copper. Little improvements over time

Not surprised but happy that someone identified this source
Geez, here is another issue for which we’ve known about for 40 or so years that requires “urgent Action” for the past 40 years already
Wake me up when we finally do something
Boomers have categorically chosen apathy in favor of their own self interests since 1970. By the late 90s, they were a wrecking ball.
Most probably simply didn’t know. A lot has to do with policies made by politicians that did know. Don’t pretend to be better, you would have done the same back then with the information you had. Remember, no internet.
lol, ok.
Despite your unfounded assumption, I’m old enough to know what it was like living pre-internet. Information was there, for those who chose to seek it out. Boomers, on the other hand, are the living definition of Dunning-Kruger. So no, they don’t get a pass. They chose to remain ignorant and uneducated, and when they gained any advantage, they made sure that those who came afterward would NOT. That’s not just a lack of awareness, it’s mean-spirited and selfish. Which fits “Generation Me,” to a T.
Well, no.
I am from the generation after the boomers but I grew up right before the Internet exploded onto the world and i can tell you that you would never see that sort of information unless you were looking for it. I know people love to shit on boomers, hence boomers being an insult word these days, but many simply couldn’t know better.
Hell, I didn’t know and believe me, I was (and still am) the kind of person that loves to read new things STEM. I had subscriptions on scientific magazines and I do remember reading articles about it being anything, scientists already knew about car tired being a problem, but it didn’t go beyond some reports. The general population didn’t know and pretending that they could have and should have known is simply disingenuous.
If you were alive at that time then you too know that it wasn’t that easy.
I disagree. People who live their entire lives being relentless bombarded by consumerist propaganda and pro-capitalist disinformation are not truly free to vote against it, nor were they given the chance. Al Gore cared more about the environment than Bush, but he was still a capitalist that supported car dependency and the military industrial complex.
Given that Gore actually won the election it’s arguable that his concessions towards climate change, that it was real for a start, was the reason the election was close enough for him to lose the election. Voters loved the comforting lie over the hard truth then and they still do.
Especially given the yahoo Trump wants to appoint that doesn’t believe in climate change even in 2024 is pretty damning of our ability to do anything about it.
So you’re absolving “Generation Me” of ever having to think for themselves? The same generation that could have educated themselves for less than the price of new car, and simply chose not to because a high school diploma was enough?
Millennials were just as heavily, if not more propagandized, and yet, as a cohort, we have skewed far from Baby Boomers (ie Millenials are killing x), while retaining the ability to be critical of the systems we have inherited. We are also far more educated and far more in debt. All as a result of Boomers subsidizing their own welfare on the backs of their children and grandchildren.
Baby Boomers collectively failed upward, soaked up benefit after benefit while telling themselves that they deserved their station in life, and then pulled up every ladder behind them.
So, hard disagree.
Which is why replacing First-past-the-post voting is so important. We need to have more then two options.
Democrats believe in democracy right? What’s the hold up blue states?
More realistically like 15 years, but, yeah, same difference in the end.
You might as well just take the long nap.
No ones gonna do anything.
We’re gonna keep wringing our hands about it, desperately shout time is running out…and watch time run out, then shrug our shoulders and go “Welp, nothing we can do about it now”
We need to convince billionaires to care. They are the ones who hold all the real political power.

Nah, just get santa to solve our crisis
Got the vasectomy already. I’m all set to become the most unreasonable person in the chaos wastes.
Action won’t happen. In fact, we’ll increase the amount of pollution!
This is the way
This makes people that harass people with vehicle drive-bys and creepy vehicle stalking just that much more destructive and shite evil.
They might as well go exploit a child to poison a puppy dog like my neighbor the state patrol trooper did.
would this apply to bycicle tyres as well? also, why is it spelled that way?
Yes, though note that tire and road wear scale with the 4th power of the vehicle weight. If a person on a bicycle weighs 200 pounds and a person driving a car weighs 2000 pounds then the car is going to have roughly 10,000 times as much tire wear (and microplastic shedding) as the bike.
Now consider that people on bikes can even weigh less than 200 pounds and cars can weigh far more than 2000 pounds (I heard of a recent electric SUV that weighs 8000 pounds) and it becomes clear that bicycles are a complete non-issue, relative to cars. An 8000 pound car is equivalent to 6.25 million 160 pound bicycle + rider pairings.
Now consider the effects of 18-wheeler tractor tailors with a maximum weight upwards of 80,000 pounds. These things absolutely disintegrate their tires. If you’ve done any highway driving you’ve likely seen the shredded debris of tires on the shoulder of the road.
Edit: as an addendum I’d like to note that electric vehicles tend to weigh a lot more than ICE cars, by upwards of 1000 pounds. This is one of the reasons I’m dismayed at the rush to EVs: it’s going to accelerate the microplastic problem even as it reduces CO2.
Yes i agree. I have never driven but have been i a car due to medical reasons, but have rode a bike and plan to bike again once im a weight that a bike can sustain (im 370 right now). ive seen thoese tire “husks” on the highway sometimes.
also, why is it spelled that way?
British spelling of tire is tyre
is that why its called the tyburn tree? a phonetic usage of the British language?
You mean the English spelling. Its their language
This is also yet another reason SUVs are bad: bigger tyres, higher weight, more wear, more pollution.
It’s also another reason to have lower speed limits: less friction, less wear, less pollution.
You want trains because they are good for the environment.
I want trains because chugga chugga choo choo.
We are not the same.
Why not both?
