When I was looking for higher load rated tires the size of the rim made a very big difference. Most high capacity tires are made for delivery vehicles with smaller rims and DRW or for large trucks (22.5" rims).
The sidewall profile is a factor with a truck if you plan to haul any amount of weight. It will take less of an impact to break the bead of the tire and provide an instant flat tire. The larger rims do result in tires that provide better fuel economy as there is less sidewall flexing that wastes fuel. This is trivial for a truck owner but a very big deal for the truck manufacturer who is very much concerned about meeting federal CAFE fleet standards for fuel economy.
When I was looking at new trucks I found that the trucks on the dealers' lots with 20" wheels all had a lot lower payload rating than the trucks with the 17" or 18" wheels so more changed than just the tires on these GM/Chevy 1-ton SRW trucks.
The option 20" tire on the RAM 2500 is 285/60/20 with a load rating of 3840lbs???????????????????????????????????????????????
