The Method HD's at 4500 lbs have a higher weight capacity than almost any tire you will mount on them, so the argument is a bit pointless. Doubly so when you consider axle ratings. Generally, the best you can hope for in the popular AT and MT profiles is a 128 load rating, which is 3968 lbs. Some exceptions to that on the high side, but few and far between like hen's teeth.
The stock Tremor wheels have a load rating of 3590 lbs, so if you mount standard Methods at 3640 lbs you're not exactly short-changing your truck or anything.
The folks who really need to drill down on their tire and wheel load ratings are the full wall, hardside truck camper folks. When it comes to fifth wheels featuring a pin weight that comes close to maxing out the payload of an F350... well that is a massive beast and speaking personally is not something I'd tow with a SRW.
Anyways, the argument is academic except for a small sliver of Super Duty owners.
My $.02... worth what you paid for it.
