This is a great downhill tire if you don't mind the weight or drag. Excellent if you live close to a bike park since you won't be pedaling up. I weigh 225lbs and ride aggressively so, for me having a hard, fat tire with lots of surface area is more important than the extra weight or drag that the tire may bring to the equation. It grips ok in a variety of surfaces from hard packed dirt to deep mud.Great value compared to Michelin's "wild gripper decent" and they are basically the same tire.
