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

581 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?

Take a nail file and file your nails. Is the file coated in nails? Well, yes, but it’s a powder, not a sticky film. If you blow on the file, the nail powder will fly away and it’s like it was never there.

It’s the same with tires. The rubber that wears off of them is in the form of fine poweder. That powder is then blown away. The tire itself will often blow it up into the air as it’s moving.
