    There’s all kinds of black dust on and near roads. That’s the worn down rubber from tires.

    Moved into a house last year that has rubber tire “mulch” all around the landscaping. I didn’t know that was a thing until then. We can pick up a piece and see part of tire brand names on it.

    So yeah, I think a lot is picked up and turned into this crap because people see it as longer lasting and more pretty than wood mulch. Nevermind what it does to the soil.

    I thought I read tires are the largest source of oceanic microplastics. But I’m not sure if that’s real

    I’ve attended a few sustainability conferences where this was discussed. The particles are typically very fine and become dust. Some of it is airborne (not good for our lungs), some settles into the soil, and some gets washed into rivers. It will likely get worse because electric vehicles are much heavier than ICE vehicles, and wear tires faster. It’s a problem that we unfortunately tend to ignore.

    Tire wear is one of the largest, along with synthetic fabrics, source of microplastics.

  8. keenedge422 Avatar

    the rubber is abraded off and is ultra-fine, like sawdust. When cars whip by on the same roads, the air currents tend to blow it to either side, where it mixes in with other debris like decaying leaves or gravel or dirt. It also gets washed away by rain to collect in ditches with more dirt.

    Most people also attribute a lot of the black grime they do see around roads (like what darkens concrete barrier walls) to exhaust and oil from cars, while not considering that much of it is rubber, too.

    it wears off slowly. when you sand something down, you don’t take huge chunks off; you make a layer of dust. driving along the road is basically an inefficient way of sanding your tyres down.

    Actually, particulate matter from tires pose a serious risk on the environment. Fishing companies in California are suing tire companies because the particulate matter from tires are killing salmon.

    Most modern tires aren’t pure rubber. They degrade to a fine plastic dust. Modern tires are one of the largest sources of microplastics that are over running the world.

    The solid particles are either burned into the ground or swept away by maintenance vehicles or the elements, particularly rain and wind. Ends up in the most common locations being the landfill, the ocean and our bodies(lungs).

    On a related note, rubber buildup on runways is a serious issue which requires regular maintenance.

    I see rubber alongside the road, in the road, everywhere. Not everyday but often enough. Usually, it’s from semi trucks and big vehicle like car carriers. 

    But the worst thing is the rubber you can’t see: in the air, water, soil, on the road surface. You’re breathing that, and it’s in your water now. 

    It rubs off your tires, everyone’s tires, little by little by little. Until it goes airborne, or is washed by rain or moved by wind, into many other places it shouldn’t be. 

    The parts rubbed off onto other surfaces can be small. You’re driving by quickly. You won’t see them because you’re not looking closely enough. But you do see tire tracks and tire skid marks, I bet. From when people brake very hard, leaving behind literal rubber traces on the road.

    To what degree are tires still natural rubber? Sure, it’s been vulcanized and has other chemicals, but how far from pretty natural latex rubber are we with tires?

    It is actually on the road. In motorsports, they talk about how the track is less grippy in the beginning of the session and once cars drive on it for a while, the car has more grip because the rubber from the tires is on the road.

  47. SolaraOne Avatar

    I bet rain and wind wash it away. In cities they also have street sweepers. The smallest particles likely even go airborne.

  48. Some_Troll_Shaman Avatar

    Some sticks to the road, some is the black dust near roads.
    Combination of rubber and brake shoe compound.

    FWIW A company I used to work for made the product to strip the rubber deposits off international airport runways. Those tires leave a lot of rubber behind as the wheels spin up on contact with the runway.

  49. LornaSkies Avatar

    Most of it becomes dust. Tire wear produces tiny rubber particles that get kicked up into the air, wash into drains, or settle on roads and soil. It’s real, and it’s everywhere, even in the ocean. You’re probably breathing a little tire right now.

    Tire dust. Major pollutant. #1 cause of microplastics in the ocean. Very bad. Worse with EVs because they are heavier. Cars are a problem.

    Outside of those lines. That’s where the rubber is

  53. flyfallridesail417 Avatar

    I’m an airline pilot, you very much see rubber in the touchdown zone of runways used frequently for landing. It’s actually a problem on some runways (particularly non-grooved runways in the tropics) because it greatly increases the risk of hydroplaning (“reverted rubber” = rubber remelts and forms liquid barrier between tire and runway).

    You also see a bunch of beads and marbles of rubber alongside the racetrack after high-performance motorsports – F1, IndyCar, NASCAR etc

    I have camped on the infield at the Daytona 24 hour race, 50 something years ago. Spent the next week blowing and flushing expensive tires out of my sinuses. By now I think I have gotten most of it.

    Yes it gets into the air.

    The ELI5 answer, You know how pencil erasers leave behind dust when you use them? Tires work the same way, they wear down and leave “tire dust” on the road. Rain and wind wash it away though so you don’t see big piles of it sitting on the side of the road.

    Unfortunately if you are interested in learning more and being a bit bummed out look into the work on 6PPD being done by Washington and Oregon. The tire particulates being deposited in the side of the road are a substantial risk to juvenile salmon and steelhead.

    It actually becomes part of the road. If you’ve ever looked at a fairly new section of pavement that was newly paved, you can actually see the rubber that was left behind from tires. Since it takes thousands of miles to wear tires down, the layers are so thin, it is unnoticeable.

  79. Desert_lotus108 Avatar

    Wow I always assumed it kinda fused into the road surface over time which I think still happens because you can see that on sharp turn, but for the most part I guess it becomes dust like all these other comments say

  80. GeneralCharacter101 Avatar

    I see plenty of comments about the micro particles that wear off tires–6ppd-Q is one that’s been getting a lot of attention lately–but I think it’s important to note: you do see rubber laying along the side of the road in some places. Any long stretch of highway you’ll see shells of cheap, poorly constructed tired that got too hot and delaminated in sheets.

  81. Blitzer046 Avatar

    I used to live about 7 houses from a freeway. Sure, it had sound-baffling walls, but after living there a year, I realised that fine black dust was accumulating on anything outside that didn’t get washed off by rain.

    I don’t live there anymore.

    The rubber disintegrates and dusts the area around roads.

    it goes to the three nations… air, water, earth… worse? our blood.

    alternatively, the rubber migrates to the same interdimensional dump where missing socks and lost pens are.

    Rubber is a massive pollutant. Think about all the roads and motorways that lead past rivers and lakes. Now think how all that rubber gets washed into said waterways when it rains. Fish, frogs and other marine animals are absolutely chock-full of plastic. Since it is a hormonal disruptor, some species of frog have like 95% female births. Hence the famous sentence “they’re turning the frogs gay”.

  112. JackBMX637 Avatar

    No professional, but I’m pretty sure that the friction of the wheels turning on the ground, braking, etc. slowly grinds away the rubber, but it’s in really small amounts which you can’t see unless they take time to build up, and they typically get washed away by rain/wind. Think like sandpaper, just really, really slow.

  113. Carlpanzram1916 Avatar

    It’s not going in giant chunks. It’s very gradually wearing into the tarmac. You can usually drive like 50,000-75,000 miles on tires. That’s like driving across the entire continental United States and back 10x. Now think of all that distance and divide it by the quarter inch or so of rubber that wears off of your tire treads. The amount being placed onto the road at any given time is microscopic.

    Around 25% of the microplastics in the ocean come from vehicle tyres.
