I ordered this tire because I shredded my front throwing my bike across a stream and needed a new one in short order. I was a little bit leery of the weight, but the 2.2 is a lot lighter than the 2.4 and not too much heavier than the Crossmark I shredded. Once I got the tire I noticed a few things right away. First, there's no way the 2.2 is actually a 2.2. In comparison to the 2.1 Maxxis Crossmark on my back wheel it looks more like a 2.0 or even a 1.95. Thus the weight difference. Secondly, it doesn't have great air volume. So if you're running rigid or tubeless, think again. Finally, you won't seat this thing tubeless without an air compressor. I wasted 30 minutes of my life trying so that you wouldn't have to. Because that's just the kind of guy I am. Make plans to have access to a compressor when it arrives.
However, on the trail it was a whole different story. I was really impressed with the performance of the tire on dry, rocks, sand and a few soft spots. It doesn't feel overly heavy, and the big knobs don't seem to be slowing it down. As soon as I went around the first sandy corner I had instant confidence in this tire's cornering abilities. So despite the shortcomings of Continental's sizing department, I was really pleased with the overall performance of the tire and I highly recommend it for your big wheels. Just buy the 2.4.
