So the often celebrated Maxxis tires have feet of clay as well as the rest?!?

Here's my suggestion-- look closely at your current tires.
Read the Maximum Load rating stamped on the sidewalls.
Multiply that number by the number of tires on your trailer.
Next time you are fueling up at a truck stop- pull on the scales
and get weighed! Note the Axle weight of your rig.

Compare the maximum load rating of your tires to the ACTUAL weight
on them when you're ready to go camping.
The difference is your safety factor.

MY tire total load rating is over 7000 LBS while my Actual weight on the
axles is 4000 LBS.
That's a nice safety cushion IMO.

I've seen trailers where the difference between these 2 numbers is
very small while the trailer is sitting on the dealers lot. With food, water
gear and other goodies loaded some have zero or a negative safety
factor

What's YOUR safety factor. No guessing. You must get
weighed and do the math to know for sure.

I apparently mis-read pwrstrokes post.
I thought he was agreeing with quoted text saying in part-
"I only had about 2000 miles on the china junk that came on my trailer"
I read that meaning his Maxxis tires had failed early. I see now that's
not what he meant.

I stand behind my opinion that the load rating/actual axle weight safety factor is more important
than brand or country of origin.

Yes, Maxxis are not "China junk", that's for sure.
But you are right about checking the actual loads on the tires and going from there. The C-rated tires on my fifth were loaded far too close to their maximum rating to be comfortable. They were Duro tires, which seem to have a slightly better reputation, but I wasn't about to take any chances with my brand new camper.
So, Maxxis it was.

It would be nice to be able to choose a tire upgrade just like you choose
color of counter tops or other options when purchasing a new RV.
Nobody wants to bring their new trailer home and promptly remove and
sell/discard a new set of tires!!

Wow, C-rated tires on a fifth wheel, I would have swapped them out too. The 2004 Wildcat 27RK that we used to own had a dry weight of 6870 and came with D-rated tires. BTW, those tires were made in Mexico.

Most RV buyers are clueless, and if the factory offered better tires, then everyone would panic that the original tires were deadly. And that might make them go to a different manufacturer.
And if the factory just put good tires on the units, they would have to charge a little more, once again maybe being the difference between selling a unit or not.
The problem is that RV buyers are not educated, and that is who the factory has to design their campers for.
Buyers will pay a little more for fancy this or that, but tires? They have no idea.
So while it irks me that the factory uses cheap tires, one of the most important safety features on the campers, I understand what they are up against.

And my axles aren't any better, loaded to the max at the GVWR.
I wonder how long before they fail?

All Rockwood/Flagstaff 5vers come with C rated tires and 4000 lb axles. This is the 4th year and 10000 + miles on the Duros that came with the camper and they seem to be wearing just fine. I am however thinking about replacing this fall with Maxxis or Marathons on our NH trip as they're harder to get in Ontario.

Isn't that how the manufacturers determine the camper's GVWR...axle rating x 2 plus dry pin weight?

Sounds like a set of 5000# should be ordered as preventive maintenance.
