I only put about 200 miles on mine and they held up fine and were really good on dirt/gravel roads, but slow on the pavement..........
So I replaced the gumwall knobbies with some Kenda whitewall road tires.........
I ran the knobbies on my commuter while they were doing road construction and they did well on this bike also..........
So I would say if you are riding mostly on crappy pavement with some dirt/gravel these tires would be fine except the ugly gumwall color. Maybe change up your saddle and bar tape/grips with a color more suitable for gumwalls?
