I'm looking for a tire similar to the Scorpion XCMH but that will last a lot longer. I ride in a lot of rocky areas, double track with loose gravel and a bit of beginner level single track with hard pack and rocks. The XCMH is perfect for where I ride, the issue is that below is what is left of them after only 3 rides. The first ride with them feels like I'm on rails cruising down gravel roads and climbing rocky hills., planted and sticky. The second ride found me sliding around a bit more but they were still great. Half way through the third ride I felt like there are patches of ice under my tires at times and I'm sliding around a lot. I keep hearing good things about the Shinko Cheater 505, the tread pattern is a little tighter though and they may not be as good on the loose stuff.
