I ve never broken a Resaw King blade but my saw has a 20 inch wheel. I also leave my blade tensioned unless I m out of the shop for a week or more.
But you might consider leaving your saws blade untensioned.Plus it is a very lite duty saw.
This is from Timber wolfs site I think.

When you are done cutting for the day, take the tension off your blade. Band saw blades, when warmed up from cutting, always stretch; and upon cooling shrink by tens of thousandths of an inch each cooling period. Therefore, blades, when left on the saw over tension themselves and leave the memory of the two wheels in the steel of the band, which will cause cracking in the gullet. When you leave the band on your saw under tension, not only do you distort the crown and flatten out the tires (which makes them very hard), but you also place undue stress on your bearings and shafts. Believe it or not; you can, and will damage your wheel geometry sooner or later and considerably shorten bearing life. You are also crushing your tires or V-belts.

Not to argue with Timberwolf but perhaps as a manufacturer they are being prudent and covering their asses against the worst possible case end user.
I have been using bandsaws commercially and as a hobbiest for nearly fifty years with sizes from 10” to 42” and have never either de-tensioned nor seen any of the above problems. My guess is that the majority of bandsaws never get de-tensioned but that’s just my guess.
Not wanting to start an argument, just surprised to read something like that so contrary to my experience.
