I believe the tire load rating capacity is where the concern is.
So unless you have compressed the springs to where the bumper stops of the frame are touching, or near, that would be my concern, and the axle should be fine.
Look at the sidewall of the tire, there it will be listed, something like Load Rating Capacity E, or something.
Then look up mfr and their weight carrying capacity on that spec, use that info per tire (times 4 on rear axle), make sure tires are inflated to recommended pressure, then go weigh the RV and get what you are empty, per axle, go from there.
Tire ratings are if the correct air pressures is present.
Ten miles or a couple hundred, if the tires are over capacity, you will never know.
A little stress the wrong way, at the wrong time, and the tire may give.
Why roll the dice with such a precious large investment?
p.s. I also believe the load capacity label, in the garage, is before any gear, supplies, and anything else you load into the RV, not just a motorcycle, or two.
Water is roughly 8 lbs per gallon, do you also fill the water tank?
That's my dilemma, looking at $3K to replace six, what look almost new tires, to a higher rated set of tires.
