Lots of tires blow out in potholes, we have a whole stack of them at the maintenance door of the 500 car rental fleet that I occasionally work at. Every one of them caused by LOW air pressure, severe rim damage because the tire did not have enough pressure to resist the impact. None where the tire blew out without rim damage.
WITH a "severe use" towing schedule, 4 days a week towing a 5,000 lb boat with various vehicles, usually a Toyota Sienna, I vote for the 44 lb inflation level in the rear. Stability and resistance to sway is greatly enhanced and completely eliminated tail wagging at interstate speeds. No reason to be one of those white knuckled drivers struggling to maintain control with inadequate pressure in your rear tires.
Yes, mine are always at 44 psi when towing!
