It gets "scrubbed off" against the road surface. Here's a funny analogy for you: It's kinda like peeling the string off a YoYo, but the "string" is a flat layer across the entire width of the tire tread. And the thin, flat "Peel" is 50,000 miles long.
You see the black stripes on concrete roadways where all the cars and trucks tires have been leaving tiny bits behind. (Can't see it on black asphalt, of course. From there, it's blown away by wind and washed away by rain, sometimes scrubbed off by street cleaners.
