these tires are mentioned quite a bit here and there and people seem to like them. my friend loned me one to try and im actually running it on back since it's a skinnier version. from the first ride it feels really good, but does anyone have experience with these? can they handle street as well as dirt? i don't want to destroy the tire, and if they hold up well i would like to get one for the front too. (did a search on this topic and came up with nothing so sorry if it's been brought up before)
