I am totally impessed with this tire.I have been invovled in the motorsports industry professionally for over 15 years. This tire works just as well,if not better, than any other tire at any price or brand. Just put 2 hours of riding in mixed terrain(hard pack, sand, rock, roots) on the rear and it still has the edges on the knobs. It also hooked up everywhere.Defintiely recommend this tire! Oh,and by the way, it mounts up the same as every other mx tire,if you know what you are doing and I have easily installed over 100 mx rear tires.
