In fact, the wheels that came with my unit are rated at 3200# each, inadequate. The only items that are properly rated on my 5th wheel are the Chinese tires, one of which has already formed a sidewall bubble at less than 1500 miles. Suggestions???
You are forgetting that 15 - 20% of total camper weight is never on the camper's tires or axles. That weight is borne by the truck's axles when hooked up and front landing gear (when parked).
At 13,572 GVWR, the MOST weight the axles will ever see is 85% of that number or 11,536 pounds (in limits for your two axles) and the tires will see 11,536 divided by 4 or 2,884 pounds per tire (again well within limits at GVWR).
At optimal loading (20%) the axles will see 80% of that number or 10,857 pounds (WELL in limits for your two axles) and the tires will see 10,587 divided by 4 or 2,714 pounds per tire (again well within limits at GVWR).
