I used to run 26x1's, they lasted me about 2 months before the flats started to be a hassle. Now I run a set of MICHELIN XC ROAD in 26X1.4 an I have only had one flat (knocks on wood) and that was because someone actually pushed something into my tire.(I have to leave my bike locked on the street a few blocks from work, unattended) I also keep a set of 26x1.95 Specialized Armadillos at my apartment as a just in case set.
