Couple years ago I bought several Nashbar Slick City tires (559x1.25) for about 9 bucks apiece, aged them a year or so and installed one on the back of my LWB recumbent after installing a liner. I get about 2500 miles out of them with no flats Probably could run them further, but I don't like to push them, and at the price....... We don't have the thorns here, but lots of glass.
