After 1800 miles I had eaten half of that poor rear knobby off my bike. I ride mostly on the pavement, and so I set about a quest to find the best true enduro tire. I wound up going with the Heidenau K-60 scout tires. Those german bastardos don't duck around. They make a 70/30 rear and a 50/50 rear. I went with the 50/50. Supposed to get 9-12 thousand miles off of them. I have 700 miles on them, and so I can't say much about that. But I can say these babies stick to the road like glue and still do a very respectable job on trails and gravel. Can't say I'd go muddin' with them, but with enough Jack Daniels anything is possible. Should happenstance require a hasty redirection across a cotton field to avoid undesirable legal encounters, then I have complete faith in my K-60s to deliver me from justice. So if you're orientation is mostly street riding with moderate dirt thrown in, or you may require a spontaneous transition to off-road conditions when the blue lights suddenly appear, then these Heidenau tires are the bomb. I swear by 'em.
