It’s not the tires and wheels increasing the capacity unless Ford “chose” to add higher rated tires to the 20s.
Actually in general if the tire OD is the same (unless the 20s are notably taller), the greater the rim diameter, the lesser the sidewall height and the lower the load rating.
And besides people are confusing gvwr, aka payload, with tow rating that is increasing the gcvwr considerably without a large or any payload increase.
My “guess” is the 2klb tow increase is from lower gearing and may have mis-read or it misprinted.
I think you need to learn what you talk about. in 2014 nd several other years the increased gvw package in my canse 11500 was only available with the 20" wheels and that was the only thing different from the 11000 gvw package. yes they are bigger 34.6" and rated higher, both rim and tire.
