I have found quite a bit of variation in tire sizes labelled the same. Some 27 1/4's are about the same width as 27 1/8's and some that are the same width are considerably taller.

I was disappointed recently when I bought some Panaracer Pasela Tourguard 27 1/4's from Nashbar. I have these same tires on a different bike and even though they are labelled the same, the new ones are considerably wider.
