Tire size Q: when is a 26 not a 26?cmgauch

I use an old, but nearly perfect Sears Free Spirit Britany 3speed to ride the .5 mile each day to the bus. The tires are severely dry-rotted & I went to replace them with some sheapo smoothies I had laying around. They don't come close to fitting, although both are labeled as 26".

Am I missing something?

Probably more than two, actually, but the two that usually cause trouble are the 26" decimal sizes (like 26 x 1.75") commonly used on modern MTBs, and the 26" fractional sizes (like 26 x 1 3/4) commonly used on old Schwinn cruisers and sometimes on other old American bikes. It is impossible to get the former onto rims for the latter without breaking the tire bead cord and denting the rim.
Thanks for the education (nm)cmgauch
