Ok Tire manufactures have been designing tires for sometime now & they all have min & max wheel sizes listed for each size of tire they offer & most have a recommended size listed. To say that stretching a tire beyond their recommendations is better is to say they don't know what the fuck they are doing! Now if they are wrong it's the first I have heard. I'm sure they have done the right testing above & beyond anything us as the consumer would ever be able to do. If tire stretching is all that great then why do the manufactures & installers not warranty the tires if they will even install them.
