It appears there is some serious misinformation and/or FUD here.

You have axles rated for 5200 lbs (or 2600 lbs per wheel)

You have rims rated for 3200 lbs.

With a 5200 lb. axle (which is pretty weak by the way), I would want a 20% tire capacity margin (I believe RVIA only requires 15%) 5200 + (5200 x 0.20) = 6260 lbs. or 3130 lbs. per wheel.
Any of the suggested tires exceed that capacity. Some actually exceed the wheel capacity.

The GY Endurance tires are more than adequate for your RV. Why insist on a 3520 lb. rated tire?
