Interesting that the highest rated axle Airstream uses is 5,000 pounds found on the 31' Classics and one of the single axle Bambi trailers. I see in excess of 8,200 pounds on the axles when loaded excluding the tongue weight. That means the axles are supporting roughly 82% capacity all the time. Makes me wonder if they will have to be replaced just after the warranty expires?
So, empty at the factory, the total trailer weight was around 7,175 pounds. Deducting the theoretical 730 pound tongue weight would mean the axles were supporting around 6,445 pounds or 65% of their capacity.
Following the logic expressed above, one could need 8,000 pound rated axles to run at 55% load. The four 16" Michelin LT225/75R16/E LTX M/S2 tires are rated for a total capacity of 10,720 pounds. So the tires would become the weak link in the suspension with the higher capacity axle rating. I have not seen Load range F or G for 16" tires.....
Makes one wonder about all the lowest bidder/lowest possible cost parts we acquired at the highest possible price assembly.
