tire size, 27 * 1 & 1/4 or 700 * 32

You can't interchange on same rim if that's what you mean. The bead seat diameter is different;
622mm for the 700C and 630mm for the 27". If you don't like the IRC's(which are ok tires) check out
the Continental Sport 1000.

What exactly is the difference between 27 by 1 and 1/4 and 700 by 32? Are these different
measurements on the same tire?

700mm is 27.55 inches. The tire I currently have on the rim is 27 inches.

Those are nominal dimensions based on ancient tires. 700c wheels are actually smaller than
27 inchers.

will a 700 mm tire work?

Absolutely not.

Sorry if this a newbie question, but I'd like to know as I gotta replace some rubber.

I have a Web article that explains the arcane details of tire sizing,

BTW any suggestions for good economical tires ($10 to 20 US)? I've seen some IRC ones for a few
bucks but I imagine these are of lower quality.

IRC tires tend to be quite good. We have a pretty good selection, see:

Well it is an old Miyata bike that still works really good for me. I intend to get at least another
number of years out of it.

I read this through this before posting, but it was still not clear to me at the time.
