If car tires are always losing rubber as they drive, how come the roads are not coated with rubber?

597 viewsOther

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?

Tire dust and lager particles are incredibly polluting. Add to that the fact that only <10% of the tire actually serves it’s purpose (to keep car moving forward and stopping) and the rest is just waste that for the most part is not managed correctly, they are probably one of the most polluting products. Here’s an article that summarizes how polluting and toxic rubber from tires is:
