FWIW I've used them on my old Husky 630 and ~ great in loose stuff and rocky stuff, ok in mud. Good on road (very good actually) and predictable in the wet. They wore quickly though, the tread looks half worn when brand new as it's not very deep.
Oh, and the yellow stripped Dakar has very stiff sidewalls, oh what fun they were to get on (and off) the wheel.
