The main reason folks opt for the 16” wheels is to raise the FW. Raising the FW will allow the FW hitch to be lowered resulting in a less “nose” high towing condition. People will also move the shackle attachment to the bottom hole of the shackle resulting in raising the FW for the same purpose. Others will relocate the axle(s) from over the springs to under the springs to raise the FW.
The reason for all these options is to allow for adjustments in the FW hitch and the FW pin box. The more level your FW results in less wear and tear on the rear tires/axle and giving better weight distribution across both axles.
The actual problem that results in a nose high condition is the newer trucks. For whatever reason, all the manufactures have built their trucks much higher than years past. In my case, I have my FW hitch at its lowest point, the axles are on the bottom of the springs from the factory, and 15” wheels on FW and I am nose high. There is a 4” difference front to back. My truck came with 20” wheels that I am certain are one of the reasons I am quite nose high.
One more thing … while trying to make the FW level, you still need to maintain 5” – 6” minimum height above the truck bed rails.
