Google "Ford super duty truck source book". Long ago I found a PDF of the "source book" for my 2015 F350, which is where I got the 3590-lb wheel rating and 3640-lb tire rating.
While talking with a local Les Schwab tire center, they said Ford/Dodge/etc "OEM" wheels tend to be honestly rated and robust, and most of the wheel failures they see are with 3rd party wheels where the ratings are suspect. When telling them I was at ~95% of wheel and tire capacity, they said I was fine, but if I was still inclined to worry and upgrade something, I should focus on the tires first.
As NRALIFR notes, Ford seems to under-spec the axle ratings, so I don't worry about being at 7K on 7K rated axles.
