Fuel Mileage with A/T Tires
I bought a "new to me" 2014 STX 5.0 back in September that has Goodyear Wrangler Duratrac A/T tires on it. They are not in the best shape and I am thinking of going to back BF Goodrich All Terrain TAs which is what always used on my old 2007 F-150 XLT 5.4. Should I expect to see much difference in MPG between these two tires. I did a little research and they seem to weigh pretty much the same. I am enjoying the fuel mileage this truck gets (19 mpg) in comparison to my previous truck (12 mpg) and don't want to botch it by getting tires that ruin MPG. Thanks for any insight.
Edited to mention that the tires will be same size

You will loose a little mileage every time you go with a heavier, taller, wider or more aggressive tire than your current tire. Shouldn't be much.

So Im guessing those duraracs are LT tires...no size mentioned.
If you don't need LT tires, then my advice is to go with a P rated tire. They weigh less, ride much better and will allow for better mpg.
I am not a fan of LT tires and only run P rated.
If you like the BFG AT tires have a look at the General Grabber AT2 tires - great tire, very similar to the BFs and it comes in a P rating.
I have the Generals on my truck for winter - they wear exceptionally well, great traction and ride smooth!

Not necessarily. There are actually several offerings of standard load or P-metric tires available in 33" sizes, depending on rim diameter. I am currently running P275/60/20 which is a 33" tire. I am considering swapping to 17" Raptor pulloffs and have been shopping P285/70/17 tires which are 32.76".

I bought my truck used and it still had the factory hankook dynapro hiway tread. I went with the dynapro at and 2cm wider, same height.
from what I can tell, lost 1mpg or so.
wider, heavier, and more rolling resistance I'm sure.

As a follow-up to the OP, I think the answer to your question depends on whether your current Duratracs are standard load or LT tires. If they are LT and you go back with the same size as you stated, I don’t think you are going to see an appreciable difference. If by chance your Duratracs are a SL tire and you go to an LT tire (which all the BFG KOs are) you may see a hit. On the flip side, if you’re running LT Duratracs and swap to a standard load tire, you may see a slight improvement though I wouldn’t expect it to be huge. That would require going with something other than the KOs though.

I've been buying tires for over 40 years. I've owned most all of them. Keep the size around 33" tall or less,the width less than 12" less than 11" is even better, avoid really aggressive mud tires, keep them inflated properly and you won't see enough difference in fuel mileage to accurately calculate between any of them. Street treads, AT's, P series or any series of LT tires. You might have to experiment to find the ideal air pressure to run especially if you go to an "E" rated tire but if you do they ride just fine and still get good fuel mileage. I've never noted a bit of difference with a heavier LT series tire vs a P series tire as long as everything else is similar.
People buy the larger tires and it hurts power, wider tires and mud terrains have greater rolling resistance, and people often drive around on heavy E series tires with them underinflated to ride better and get poor fuel mileage then blame the problem on the wrong thing.
