The original K60 I had went 7000 miles and had more tread left when I switched to the Big Block. That was the best tire I've ever run on my bike but they've now ruined it with the center tread.
The Big Block has been fine but I'm not expecting many miles out of it.
Now it's time to try something else. This will be it when the BB wears out.
