I have been running a Conti Gatorskin 26x1.1 at 105psi on the rear of my LWB Bacchetta Belladare recumbent and like it a LOT. The narrow and fast tire is just about impossible to put a hole in and so less flats, and since I'm using the bike as a commuter, it's the right tire for me. HOWEVER, I'm just finding that I'm beating the heck out of my new rear wheel, and have just ordered a Schwalbe in a 26x1.75 size to try. I'm a BIG guy, 6'-4" and about 260 lbs, and so much of the load is on the rear wheel, so I'm going to try the bigger cross section tire, and a bit lower pressure to try and protect the rim
