I bought two and one had a casing defect. Sent it back and lost my tracking number. Can't remember if it was Performance or Supergo that sold them to me, but they never saw my return apparently. Otherwise, I think it's a great tire. Nice volume and hooks well from hardpack to tacky terrain. Rolls quite well. No flats. No complaints. Bought them by suggestion of one shiggy.
One ride on mine so far pretty good. Seem to grip really well to the slick roots and rocks we have around here. (maybe the "gold" compound is super grippy) FYI I got them for $15 each at greenfish sports which is a smokin deal. These are the 2.3 versions kevlar bead.
