I know it's only a few months for winter but I have heard good things about the tread wear and road noise in good weather too. I can take that in trade for the peace of mind. Maybe I can gain some of it back with my next mods. I'm looking at re-doing my front grill block and adding an air dam. That and bypassing my A/C compressor. I'm still investigating trying to lower the truck 2" in the front and 2" in the rear. That may now be possible with the taller tires but it looks like I have lots of room in the wheel well. I'll just have to make some measurements with how far the wheels travel while at full turn and see. Still....30mpg fairly consistently with a 17 year old truck is pretty darn good. Let's hope these new tires don't lose me to much.
Nothing wrong with not maxing out your efficiency. Most here are not looking to redesign their entire vehicle for max FE, but to improve on their current ride. If your life requires you to sacrifice a lil' mpg for certain reasons, then do so and improve on what you have to live by

I have done research in the past on FS D A/T's as I was looking into them for my truck (they were the cheapest all terrain by far). The info that I found over and over was a slight decrease in FE, around 1 mpg from highway tires.

Recovery modding is a good mindset. All those should add up to an increase and you'll have better FE than before! Just slowing down by 5 mph would probably balance out the effects of the A/Ts.
