I have a Forte Pro DC front tire that I've ridden for over 4000 miles... it refused to die. I'm on my 3rd rear Continental Ultra Race tire in the time it's taken me to wear out the Forte.

That said, it's heavy compared to other options out there and the black stripe down the middle is not centered (and is lopsided at places). But for a $15 training tire it was money well spent.
