What are you trying to figure out? The wheels don't change the payload
I'd say that is true, if it weren't for the fact that you can often find wheels that will fit a given vehicle that were designed for a lighter vehicle.
Bro finds a wheel he likes, but website doesn't list his brohicle. So he looks around and finds a different vehicle with the same bolt pattern and similar offset. Or orders a custom offset. Mounts browheels to his brohicle without ever realizing that wheels designed for 2800lb car can't deal with 4200lbs forever. Maybe never has an issue, second owner notices what appears to be a surface crack. Or doesn't and wheel implodes without warning. Or self destructs when the original owner hits the first pothole. Or never, ever presents a problem.
Inside of the wheel is stamped with the weight rating.
No idea if the various Ford wheels for the F150 meet the max rated configuration, but I believe there was a thread on some of the tires not being rated for the heavier configs.
The stamping on the wheel will tell the story on the wheels, and the tires are marked with a load index.
Gross Vehicle Weight Rating,(GVWR) is the maximum weight of the truck. Gross Combined Vehicle Weight, GCVW is the maximum combined weight of the truck and trailer. You don't see the 2nd number used as often anymore. All things being equal the GVWR will be the same as long as the wheels and tires are up to it. It doesn't matter if the wheels are 16", 17", 18" or 20". But if you go to a larger diameter tire it effectively changes the trucks gear ratio and that could reduce the weight of the trailer the truck can tow (GCVW). The same overall tire diameter and width can be accomplished with any wheel diameter.
I suppose the spec sheet you are looking at shows a larger diameter tire on 17" wheels than on 18" wheels. Your 4X2 truck with 18" wheels came with low profile tires, the 17" rims at the time your truck was built were meant for 4X4's that used taller tires. Of course today they offer 4X4's with 18 and 20" wheels and taller tires.

This is very true, especially when it comes to Super Duty wheels. I was watching a video of a tow company pulling an F250 out from under a 5th wheel trailer. A search of the trailer found that it was WAY over the payload of the F250, and after they got the truck righted, the left rear wheel was shattered. It was not cracked, or split, it was in pieces, and the tire was behind the trailer. It appeared that the truck was making a turn when the wheel gave out and the trailer bowled over the truck, ripping the hitch out of the bed. They were clearly aftermarket wheels, show wheels, not work wheels. It was also lifted, so add all that up, and that is one totaled out expensive truck. Trailer survived though without a scratch.
I've only looked at info for my 2008, but I believe that Ford specs intended for those adding bodies to frames exist for newer products as well. Weight capacity of 2008 factory wheels
Some of those wheels are under my axles GAWR, usually they are higher when combined. Something to keep in mind if putting on earlier model wheels on a later gen truck. My 18 has a 4050 RGAWR. Glad you posted, it also shows what I mentioned a while back in a Limited tow thread, the wheels are the weak point in towing as combined they are only 3750 pounds capacity per axle. Now I need to lookup the wheels off my 14 to see what they are rated at and compare them to the wheels that came on the 18. They should be fine since that truck had a 4050 axle as well.
