Yeah, just to echo R6G, with a little more specificity. Hutchinson makes a 26x1.3" tire, which is to say 650x32 or33mm. The tire is called the Cross Comp.
CyclocrossWorld.com sells them for 40 bones, but is currently out of stock. A Froogle search turned some up at fullcycles.com for $37.77 each. I think I got mine from Speedgoat, if I recall correctly, but I no longer see them there.
BTW, I really like mine--I use them for both Short Track XC, and the occasional cross race thet is technical enough to warrant using my hardtail.
