Question:
Where does the rubber of the tire go that wears out from driving on the road?
What effect does this "rubbed off" rubber have on the environment?
Replies:
You can see rubbed off rubber patches wherever cars skid - skid marks are
everywhere. The rubber tends to stick to the road, or gradually blow off as
dust. I do not honestly think anyone has ever thought about the environmental
effects of rubber dust, but I could be wrong. A much bigger problem is what
to do with the tires after the tread wears off. And the exhaust gasses from
cars probably have a bigger environmental impact than rubber dust. One thing
you can do with old tires is to recycle them into asphalt and use it to pave
roads - then you not only have tires on the road but IN the road too.
