Tire engineering question.
So I go and get rig weighted and inflate rear tires to 10% over psi suggested in load and inflation tables. Driving along and whats that BOOM noise? Got a blow out on the rear. In a miles long ...

I DID NOT HAVE A TIRE FAILURE. I keep getting told to run tires at much higher pressure in case I get a blow out, makes no sense.
Your tire failure may have been totally unrelated to air pressure. Still, I am curious: how did "10% over psi suggested in load and inflation tables" compare to sidewall max pressure?
In my mini Toyota sidewall max psi is 65, load and inflation table load range D tire calls for 39 psi, I run 43 and use TPMS.
Sorry, but in my mind a blow-out is a tire failure.
I am always curious about how folks use load/inflation tables. I see a lot of reference to them. I go with the advice of my neighbor, who is maintenance director for a large commercial truck leasing company. He manages the tire program for a fleet of several hundred tractor/trailer units. His advice to me for my motorhomes has always been to inflate to sidewall max pressure and go. Under-inflation equals excessive sidewall flex, equals excessive heat, equals blow-outs.
Sorry your neighbor is ill informed.
