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.
Tyres are made from synthetic rubbers which are plastics.
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.

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.
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.
Microrubbers sounds like condoms for guys with unfortunate situations in their pants though
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.
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.
Tires also used to last longer. They are designed to wear out faster now.
This is so far from the truth.
The real reason is cars are heavier. The more weight, the more wear on the tires. You can only make a tire compound so hard before they become uncomfortable rolling chunks.
In the 70s when the fuel crisis hit, cars were very inefficient. Heavy steel and heavy engines that guzzled field. As the technology has progressed we use composite materials to make them lighter where we can. Some of these materials are more expensive than others, so you won’t find them on all models. Magnesium and Carbon fiber for example. We started to make cars lighter.
Then there’s features, creature comforts, etc. We started adding more and more fancy features over time. These all add up. Heavy sound deadening pads are placed all over the bare chassis. Rip up your car’s carpet, underneath you’ll find them. They’re in the door and behind the dashboard. There’s even foam in the A, B and C pillars. We figured out that we can make cars quieter. Now that we can make them quieter, let’s add a lot of creature comforts. Power, heated seats and mirrors. Power windows, powered lift gates, and anything else that’s powered. These require electric motors. Not sure if you’ve ever seen these electric motors, but these are actually quite heavy little things. A few speakers is now almost a dozen in many models. Lots of trim pieces that make the car more aesthetically pleasing add weight.
Safety is a huge factor as well. One or two airbags has turned into about a dozen. Extra beams that are used to dissipate energy around you in a crash. My car has 8 alone for just the front driver and passenger.
Got a hybrid or an EV? These absolutely demolish tires because the additional components adds a lot of weight.
Even though we got better at making composite materials and reducing weight where we could, our need for creature comforts and advancement in technology has caused the overall trend for a car’s weight to go up. This information is readily available if you’d like to search the Internet.
A set of tires wear endurance has only gone up over time. But because of a car’s weight, it reduces its ability. Your driving habits also greatly impact how long your tires will last. Do you have a Rivian or Tesla? Go easy on the acceleration and showing off with the spirited driving. You can make your tires last less than 10,000 mi. Do you add additional weight? How long is that additional weight being hauled around? In other words, if your trunk is full of stuff, clean it out. You’re increasing fuel consumption and increasing tire wear.
But electric cars will fix everything. Thats what electric car manufacturers said!
Trains seemingly solve all problems that were created by a bunch of rich people
We are far from good: Cars ruined walkability. Most suburbs are under constant tyre roar within a kilometer from a freeway. Stroads are hideous and biking there is dangerous.
Tyre dust went onto fields, into crops, we ate the dust, gut illness became common. Heard of gluten free? People are sick.
This would be good: https://www.quora.com/What-new-types-of-public-transport-could-there-be/answer/Harri-K-Hiltunen
But we let the free market lock us into a technological dead-end. Ending the market religion in state affairs would be good. Some things need a 100-year plan. https://lemmy.world/comment/10858248
I’m not arguing whether cars are good or bad for society as a whole.
I’m just saying that if the choice is between internal combustion engines and electric motors, it’s a no brainer.
The only thing I see amerikans taking ‘urgent action’ on is making sure a few select convicted criminals avoid doing any prison time.
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.
I learned recently that speed limits are determined by studying the speeds driven and setting them at the 85th percentile.
So what we can do to lower speed limits is to find a place they’re doing a traffic study and repeatedly drive over them at very low speeds.
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.

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.
