Well as far a kiss that's why if it's that close spacers would be the way to go and load range G is safety first I would never put my family in that situation like running E range tires. You also got to remember most people talk and never done it. Remember putting a superior load range is not unsafe just smarter. Remembered when sent out as a cut away just cab and frame and most cases not even a gas tank. Then how is ford knowing what GVW is will really be? I will put you a question do you have a light duty truck like tires say or do you have a real truck then make you choice. Also remember this is not a car driven daily it sits for some time in places.
