Maybe you could take a look around at what mfg are doing these days; Chinese tires with a 65 mph speed rating used on campers that empty use up about 80% of there capacity. In my case, loaded ready to go, I had 6875# on four tires that were ratd to carry a max of 7040#. Equally divided each tire would have only 41# of reserve capacity IF the torq flex axles equally divided the weight. And I know some weight is carried by the tongue; but the mfg are cutting corners too close for me. Also if you look at the weight of the smaller single axle campers you see the same thing, tires carring 3100-350000# on two tires rated to carry 3520#; again made in China whith who knows what for rubber, speed rated to 65mph, months of reading on here and elsewhere about there failures, It was a 'no brainer' for me to choose an upgrade to a quality, non chinese, 8 ply load range D tire which happens to also be rated up to 99 mph.
