Looking for facts - not guesses. In the event of a flat tire, What are the ramifications of using a same spec tire of a different brand but that has an outer diameter up to 1/2 " less than the origin...

.... What I am asking is what is the harm, if any, of installing the slightly smaller diameter tire in an emergency and running for a few hundred miles? What is the harm if I leave said tire on indefinitely?
If it is an emergency, I would think you would only be running a different tire for maybe 50 miles to a garage to get a replacement -- not a "few hundred miles".
If there is really such a small difference in size, you could probably run the tire without an issue. Think about when vehicles "blow" a tire, and get a replacement. That new tire most likely has 1/4 inch or more thicker tread than the older tires on the rig - and people do that ALL the time.
Note the word "probably" in the above paragraph... You SHOULD get tires all the same size, age and treadwear.
