It rides smooth on pavement and well on dirt. It takes considerably less effort to pedal compared to the flat surface road tires I had.
Pulled my Dad's old Raleigh out of the garage last month. Tires looked like they had leprosy they were so dry-rotted, bummer. Luckily these replacements were cheap and easy from Western Bikeworks. Now I have a working town bike to go get that growler refilled. The black sidewalls are nice, stay looking clean. Pro tip if you are fixing up an old bike like I was, just go ahead and replace the tubes AND the rubber rim-strips (covers the spoke heads) cuz they are going to be rotten too when you get in there.
I got these for the Oregon Outback. Kept them on after, they work for most conditions, probably not mud though I haven't tried. I have 700x40s running very low tire pressure off road with good results. How low? Your on your own there, buddy. Depends on a lot of variables. In my dreams this tire would be available in 29!
I'm not aware of any reputable objective report that shows that one brand of butyl tube is better than others, so I don't see the need to pay more. Mine have worked fine as tubes go (including the ones with the name Kenda printed on the tube but with a different name on the box), which is to say, they will puncture when pierced by sharp objects, like all tubes.
