Our Outlaw gets loaded pretty good, carrying two motorcycles, full water supply, and water is nearly 8 lbs a gallon, plus everything else we take.
I never really thought about what the tire's can withstand, until I started reading these threads.
So I do want a safety factor.
But I could not find a definite: this tire load rating "X" equals this weight range capability.
My search took me to the differences in air pressure, combined with manufacturer, then onto history of ply ratings, to things are rated differently now with modern materials that equal old way...
It just eluded me that's all, I am sure the info is out there, maybe someone can shed some light with a link?

Then, there is the scare factor in advertising, to prevent those tire blow outs you should...
Is it that common of a problem?
Then, is it tire age factor?
They do develop a dry rot and cracks.

Meanwhile I carry a spare, and I will get something like Rickson Tire recommends as an upgrade, it just will take a while to fit a budget, first things first.
Besides about 65 mph, or less, is all I am comfortable driving the RV.

Ours came equipped with Michelin 225/75-R16, load range E, and now have 12,000 miles on them.
75psi in fronts, 80psi in rears.
