I have to replace my tires every 60 000-100 000 KM as the tires wear down and the rubber comes off as I drive. If this is happening with all cars, why arnt the roads coated in rubber? Is somebody cleaning the tire rubber off the road? Is it getting washed away from the rain and into drains/the ocean? How long does it take for rubber to degrade that has come off the tire?

Basically, the road turns into a giant Slip ‘N Slide when it first starts raining because all the rubber bits from tires mix with the water. Give it a bit for the rain to do its thing and wash away the slippery stuff before you ride again.

Tires are small and the road is long.

If you ever go to an oval race, you would know where the rubber goes when it leaves the tire. You’ll have the little black bits stuck in your arm hair, in your drink, and all over your clothes.
Those bits don’t adhere to the road, its more like rubber bits the size of grains of sand. They get thrown off your vehicle at 60mph or so, they’re going to get thrown off the road mostly.
You lose skin cells all the time by just touching things. If you theoretically made everything out of skin it wouldn’t prevent you from losing skin cells. You literally lose skin cells during sex yet the other person also has skin. So…why would having rubber roads prevent rubber from wearing down?
There are road surface materials using, in part, recycled tires. They last three times longer but cost twice as much. The catch is politicians literally kicking the problem down the road. They don’t want to spend the money when a successor will get credit for the savings.
Not what you asked. But fun fact: some asphalt actually does contain rubber within it. [Link](https://calrecycle.ca.gov/tires/rac/)
You replace tyres every 60-100k km? How the hell? My last brand new set lasted me 10k, hoping for another 10 after rotation
If you’ve ever lived near a busy road, you know that anything you leave outside gets covered in a fine, black dust. That black dust is primarily tire rubber. Tire wear causes tremendous amounts of this dust.
You’re going to see a lot of talk shortly about tire emissions. There was a 20+ year study done on why fish are dying in Washington State I think it was. They’re dying from toxic chemicals in tire rubber dust getting washed into the river during rain.
I used to live close to a busy road. The tires on all that traffic turn into fine black dust which covers the house, windows, and everything else nearby.
