18's or 20's
I have 2014 f150 screw 6.5 foot bed 6.2L max tow, off road package 3.73 gears. I am thinking 4-6" lift and 35" tires would 18" rims or 20" rims be better for towing and or hauling will be pulling 8000...

Your original Q was about going with 18 or 20 inch wheels with a 35" tall tire.. As has been said, 35" is 35".. They make 35" tall tires for 16" wheels too.. ;)
How much sidewall you have seems to make the biggest difference that I've found towing with my stock 20" wheels.. Compared to the same height 16" wheels I had on my old truck, I like the P rated 20" tires better than the E rated 16's... ;)
As to the effective gear ratio change by going to taller tires, that is true and you will have to re calibrate your speedo/odo if you want accurate readings... Your trans shift patterns will also change and you will be like driving with a 3.42 gear ratio with stock height tires, so if you've been running taller tires than stock for over 20 years, you should already know this???
Anyway, it sounds like you know what you want, so go for it... :)
