great Utah tire
I mounted these up to a set of Stan's Flow rims and have been riding them in Salt Lake and Moab for a few weeks now. They mounted easily, but I recommend using a compressor as I couldn't get them to seat with my floor pump. As for performance, they're fast and grippy on everything but wet rocks and roots, and they wear like iron. Still had the little hairs on the front after two full days of slick rock riding. Good tire for dry, hardpack, sand and loose rock riding like we have here in Utah. The 2.2 size seems pretty accurate; a shade higher volume than my old Maxxis Ignitor 2.1's.
