just took a 205/60 Triple tread off (not to the wear bars yet)two weeks ago with 41.5k miles. I am NOT easy on tires... my last BS front lasted 6500 miles, my last rear MC tire (also a BS)went 8k. I rode the TT harder than the MC, just because I could!
I didn't put on another, as I just wanted to try another tire. BIG mistake. I am shopping for another TT.
It's downside (for me) is it doesn't like uneven pavement and will follow imperfections worse than some of the other tires I have ridden. Obviously a concern, but I AM looking for another... you decide for you.
