Dnver and others,
Performance is labeling one of their current house brand tires as a "700x26" but, upon mounting it, it looks like a fairly narrow "25" though I haven't taken any calipers to it. Which reminds us that tire manufacturers take a lot of liberties and their stated measurements often are skewed. Anyone familiar with older Avocets or Paselas recalls that their tires were usually one size smaller than what was labeled.
BTW, my experience so far is the Performance tires above are a pretty good value...$18 on sale, belted, and no more flats this summer than my Conti Ultra Gators or Rivendell Ruffy Tuffy's.
