I'm interested as well. They look pretty wide for 2.5, and the options are getting even slimmer for wider 24" knobby tires. I bought a few extra 24x2.8 tires a few years ago, and just mounted the last ones. The Specialized Big Roller I have on back is pretty hard to get now without spending a bunch on shipping, and the CST Fringe is only good for the front, since they wear out at around 1k miles when on the back (but lasted 5k when on the front, although completely bald at that point).What tires are those?
The 24x3 Duro DH and Razorback, or the 24x3 Halo Contra are likely my next tires, and those are rare and expensive as well, so a wide 2.5 might work.
