This sounds like a no brainer, but I figure I better be careful. Thank you.

Yes. The ERTO measurement is on essentially every tire (ex: 630x28 for a 27 x 1 1/8) the larger number tells you whether two tires fit the same rim. Sheldon's site explains it all There are practical limits, as can be seen in the red and green chart most of the way down the page on http://www.sheldonbrown.com/tire-sizing.html.

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

Yes, the 1 1/8" tire is about 5mm smaller in overall diameter and width compared to the 1 1/4" tire. Both tires will fit the same wheel without any issue.

If you ride on gravel or trails, you will miss the larger tire. The smaller tire will be less secure on loose gravel. If you ride on pavement, you won't have any control concerns.

Actually, how much smaller it is depends very much on the individual tire. There's no standard that says the tire must measure in width what the label says. The lighter tires of a given size sometimes achieve their weight advantage by being a bit undersized.
