people will look at this study and say ‘oh so EVs are even worse than ICE cars!’, when the real answer is just less cars
Micropastic is one out of many issues. CO2 is definitely more pressing, where BEV clearly are better. In other words: BEV are better compared to ICE and still crap compared to bikes etc.
less cars
Sadly, that thought is absolutely incomprehensible for many many people, including most city planners. We truly live in a silly timeline.
The answer is tires made from different products not necessarily less cars
What materials could you possibly use other than rubber compounds?

Both are technically true.
EV’s are worse on average because they are about 30% heavier than their ICE equivalents, so they’ll go through tires faster.
But because of that, they’ll also wear down road surfaces faster, requiring more construction thet emits, and requiring more use of concrete.
The weight of an EV depends on various factors, such as the size of the battery pack and the overall design of the vehicle. Some EVs may be heavier due to larger battery packs, while others may be lighter or comparable in weight to ICE vehicles. it is not accurate to generalize that EVs are heavier on average and therefore cause 30% more tyre dust (wtf did you pull this number from).
Extremely heavy vehicles, such as commercial trucks and buses, cause the majority of wear and tear on roads. Damage caused by the shift to EVs is likely to be marginal, especially when compared to the damage caused by these large vehicles.
Cars had a weight problem long before electric vehicles with their heavy batteries hit the road. The real issue with tyre dust is the overall trend of heavier vehicles, not just the introduction of EVs.
Larger electric vehicles, those weighing over two tons, are responsible for far more wear on road surfaces and emissions of tyre dust. However, this is not solely due to EVs, but rather the general trend of larger and heavier vehicles. the trend of SUVs is far worse and these cars on average are heavier than an EV sedan, which the absolute majority of evs are.
Totally agree that vehicles should be smaller in general.
Nobody needs a pickup outside of industry and agriculture. I don’t give a shit about your once-a-year camping trip where you drag your second-mortgaged house-on-wheels to cosplay rugged living. Get a fucking a tent.
Nobody needs an SUV and the only reason they’re “safer” because everything is so oversized now that it’s just a matter of relativity to other vehicles.
Anything larger than a station wagon is simply excessive for 99% of drivers.
more trains less cars reason #938
Indeed, the scale of these emissions is significant. Particulate emissions from tires and brakes, particularly in the PM2.5 and PM10 size ranges, are believed to exceed the mass of tailpipe emissions from modern vehicle fleets, as per a study published in Science of the Total Environment this year.
Are they comparing PM2.5 particulates from tires to PM2.5 particulates from tailpipe emissions? I could understand that, but not that total particulate loss from tires exceeds the total mass of tailpipe emissions.
I guess it might be possible since there isn’t something like a catalytic converter for tires (or brakes) and they could also be including EVs or bikes etc. which would inflate the figure
for brakes this totally makes sense as the bottom of cars tends to be covered in brake dust but it would imply EV’s with regenerative braking would be an improvement.
Yeah, but tires and brake pads aren’t replaced for 20,000 miles or whatever. If you assumed that you lost the mass of the entire set of tires, you’d be burning through 400 gallons of gas at 50 MPG, 800 gallons at 25 MPG in 20k miles. Burning through that much fuel would produce much more mass than one set of tires.

This is why I’m anti bike in addition to being anti car. You have two legs, that is all you ever need. If it’s too far for you to walk then it’s not worth going.
Are you also anti-shoe? I imagine all rubberized treads would do this to some degree. My guess is that temperature and speed matter.
I guess you could use clogs or geta or something.
Wait you guys are still wearing synthetic shoes?
The forces on car tires are much greater than on bike tires because cars are much heavier and go faster.
Look at the thickness and width of a car tire vs a bike tire and you’ll be able to see how much more material is worn off into the environment during the life of the tire. It’s magnitudes worse in the car and people are absolutely doing the environment a favour switching to alternative transport.
Yeah but then our oceans would be filled with sneaker dust instead of tire death and we’d be right back to square one!
One word: plant-based moccasins
Maybe we can get plant based tires
Latex rubber?
That’s like two and a half words but ok
My ENT office/Surgical center is across town. Are you suggesting that I walk for three hours with a sinus infection to an upcoming surgical appointment? And then walk home afterwards?
No, you have a medical need. But others do not.
Whew! Good news for me! What about other people with medical conditions though? Or… say… the handicapped? Would you suggest wheelchair-bound people just wheel their way across town?
Make wheels that aren’t plastic. I have no problem with natural rubber tires.
