Several comments on here about using E-rated tires. Just for general information if you special order a 4wd F150 you can get it with load range C LT tires (LT 267/65 18C) for $295. This is much easier and may be less expensive than swapping tires on a brand new truck.
Interestingly though, the 2019 Towing Guide shows that you have to have 20" tires to get the max rated tow capacity. I have not been able to find out what the tow capacity is with 18" tires of any sort and my dealer can't tell me.

I am not sure what you are trying to show me but I was referring to all the blocks marked with footnote 9 which says 20" wheels required. What would those numbers be if you don't opt for the 20" wheels? Of course, I am mostly concerned with the 3.5 Ecoboost with max trailer tow package which gets the 3.55 rear end.

The 20 inch wheels as you have stated are required to get the highest GCWR(18400) and tow capacity(13200 for 4X2 and 12900 for 4x4) in the 2019 150 when paired with the max tow package. Now with the 18 inch wheels they both drop. The GCWR for a 4x4 is then 16200 with a tow rating of 10700. The 18 inch LT tires are just an added option for stability with the non HDPP. Those LT tires also take away from the trucks payload as they weigh a good 12-15 more lbs each on avg to drop the vehicles payload by a good 60lbs just for tires.
YUP, what he said. The chart seems pretty clear.
I'll add one thing though, according to Ford published info, the tires add a total of 43 lbs (10.75 lbs each).
