Your new tires look great!
The /70 gives an extra 1" of tire diameter (.5" "lift") and fits without modification on a Trailhawk. I don't know if there is a fitment issue with AD1 or AD2. It's the same width as stock. The KO2 /70 is also load-range E. It's heavier and has thicker sidewalls. There's also about a 3% change on the speedometer (actual speed at 60Mph on the gauge is closer to 62Mph).
I have the KO2's with the /70. It fits with no rubbing. I do have a lift. I get .5 additional inches of lift with the 70's. I have also noticed the speedometer effects as well. No big deal, but remember when running them that it does exist.
