I have heard great things about both these tires, but the choices in 24" are more limited. Now that I have been riding the schwalbe stelvios for a while I have to say so far so good. They roll real nice, and so far no flats. While I can inflate them to 145, I found the ride too harsh and that I didn't have enough contact with the road so I have been running them at 120. Anyone try the terry tullus tire in a 32 width? I am thinking of putting one on the front of my touring bike, with a panaracer pasela tourguard 32 on the back for city riding. Currently I am using the 25 wide paselas without tourguard on my touring bike/commuter.
