UPGRADE from LT225/75R16 D Rating
Good Morning. . .Wanting to go to a quality tire that either has a "G" load rating of that size or a larger tire if it will fit with dual rear wheels on a 2007 Chevy 3500 Express frame. Suggestion...

Tire blow-outs are usually caused by old age failure or hitting road debris. A heavier load rating won't do anything to help with either of those things.
I've heard others say the same thing.
However, I find it highly counter-intuitive that a heavier load rated tire isn't built intrisically "in a stronger way" such as to not only hold higher pressure/higher loads if one cared about that ... but also as a not-talked-about bonus be more difficult to blow out from road debris and also maybe last longer before old age failure.
I would feel A LOT more secure by running Load Range G tires at 80 lbs. on the rear dualies of our Class C over running Load Range E tires at 80 lbs. on our rear dualies. I'd like a tire designer to explain to me (if they could?) the physics of why a G tire at 80 lbs. inflation would not be a tougher tire than an E tire at 80 lbs. inflation.
Do you know of specific commercial Load Range G tires than can be run at 80 PSI? I've not seen the inflation tables down to mininum allowable pressure, but almost all commercial tires Load Range G and heavier are steel bodied, and will quickly fail from metal fatigue in run below specified minimum inflation pressures, or run overloaded at full pressure (e.g. what happens carrying the full weight of a dually after the other tire fails).
This is something you will have to watch carefully even with a Load Range E having steel body cords, such as the XPS.
