BFG AT 275/65R18 experience?

[2016LTCC]

Does anyone have experience or thoughts to offer on running BFG 275/65R18 tires with level kit? Do they ride overly rough and how are they on the highway?

I've had my 275/70 for 3 years now still have 12/32 tread (only drove 18k on them) they ride smooth can barely hear them and do great in all weather conditions highway is great too!

I just got my KO2s in 275/75r18 about 4 days ago. Very happy with them so far. The 275/65r18 is about 5lbs lighter and 1.2 inches shorter (https://tiresize.com/tires/BFGoodrich/All-Terrain-TA-KO2.htm) than the 275/70 . Mine ride better than the stock Goodyear SR-As did, but I also have bilstein 5100 shocks installed on the 3rd highest setting (had the stock tires with those shocks for ~50k miles and the KO2 is more comfortable). They are quiet at highway speeds too. I can only hear them when doing 20-40mph, after that I can't hear them over the wind. You will see a decrease in city mpg because these tires are much heavier than the stock tires (my SR-As only weighed 35lbs). I still see about 21 hwy mpg with 3.08 gears.
