First, the numbers you wrote:
16X7J = 16" diameter and 7" wide, with a J type flange.
96GA-1007-BA-3906 is Ford's part number.
There might be load information either on the back side of the rim, where I suspect you got the numbers above, or perhaps in the drop center which would be covered by tire when one is mounted on the wheel.
- BUT -
Unlike tires, it is NOT required for any load and/or inflation limits to be stamped on wheels.
So I don't think we can answer your question.
However, I do know that Ford (and other vehicle manufacturers) get wheels appropriate for the bolt circles - that is, there is enough load capacity for EVERY wheel made of a certain bolt pattern. So unless you are building a vehicle from scratch or extensively modifi=ying a vehicle, if the wheels fits on a vehicle, it has enough load carrying capacity.
Perhaps it would help if you told us why you are asking this question.
