ya man! you got decimals, you need fractions. like DougC says,its hard to go wrong when you shop by ISO number.. :mrgreen:
It's farmore complicated than that. A list of so-called "26inch"
bike tires, and their actual inner diameters in mm:
s2 aka ballooner aka mountain bike aka "just 26inch"= 559
s7 aka 26x1 3/4 aka "middleweight" (same diameter as 650c, which are too skinny to be called 26")= 571
650b, which the Brits used to call 26x1 1/2"= 584
26x1 3/8" aka EA3 aka 650a aka "lightweights" (non-schwinn)= 590
s5 aka s6 (same size, different look) aka "lightwieghts" (schwinn-specific size)=597
I count at least 5 different diameters of 26" tire, each with an alias or two. :shock:
So, yeah, it's more complicated than just decimal vs fractions, although pretty much the decimals are interchangeable with each other; once you get to fractions, you gotta measure. If the tire was made from the 1980s on, it will probably have a actual-size metric measurement on the sidewalk somewhere. As in, a 26x2.125" will also have a 54x559 on it somewhere...
As for the OP, well, I'd say your best bet is to measure your rims diameter to make sure you got s2 rims, then order up some decent quality rubber. My current favorite *cheap* balloon tire is the Cheng Shin c241, with the knock-off BFG tread pattern, available in all-bloack, white wall,and occasionally other colors as well.
(Not nearly as good as my Fat Franks, but they come in at like 1/3 of the price!)
